Ghetaldus Zagreb King Regula L

For introduction to Ghetaldus Zagreb cameras, see Ghetaldus Zagreb King Cameras page.
For information on specific camera models, click on these links: Regula IIb, Regula IIIa, Cita III, Regula L, Regulette.

Based on specifications and considering only Ghetaldus King cameras, the Regula L seems to be an updated and upgraded Regula IIIa. The lens is still a triplet Ghenar, however, it's 2/3 of the F stop faster with a maximum aperture of F/2.8. The viewfinder has bright frame with a parallax correction mark and is bigger, which looks nice but has a downside in form of a significantly darker view. The shutter moved from the top plate to the lens barrel. The film reminder is still located on the film rewind knob while an exposure counter was moved to the bottom plate of the camera. Film advance and shutter cocking is performed by a lever hidden in the camera body.

Regula L (GRL100 variant) looks somehow more modern with it's clean top and shaped lens plate.

Some Regulas L are equipped with a Prontor-SVS shutter adding the slow speeds up to 1 s, which is significant improvement that would normally cause a model name change - but evidently not in Regula L's case. I have no clue about pricing difference, however, from a small serial numbers sample I gathered Prontor-SVS doesn't seem like an evolutionary change but rather coexistence of higher and lower spec models. Or even an exemption in a small production batch.

Evolution of Ghetaldus Regula L Production

I found Regulas L in a Ghetaldus leather case, but with a Cassar 1:2.8/45mm Steinheil München lens. At first I thought it is a coincidence and someone just replaced the ever ready case, however, I spotted several such specimens on the local internet selling sites. The L series cases are also different compared to the III series, since a hole for the exposure counter is made on the bottom side and "Regula L" is embossed on the upper part. The ones that had lens caps, had Ghetaldus ones. These Regulas L have the older style of the Regula's L body (GRL100) which was made mostly out of metal. One distinguishable feature is less leatherette like surface and more shiny metal on the front side.

It turns out there are also Ghetaldus assembled Rodenstock Trinar Regulas L.

All these Regula L cameras came in Ghetaldus cases with Ghetaldus lens caps, however, only two of them have Ghetaldus lens.

I still couldn't resist to acquire each of these "Ghetaldus Munchen" and "Ghetaldus Rodenstock" Regulas just for sake of comparing them to the Zagreb Regula L.
What I figured out is that front body metal plate design can vary in height. "Ghetaldus Munchen" and "Rodenstock" have red 10 and 3 meters engraving on the distance scale while GRL 100 and GRL 200 have all white. Presence of 20 m engraving also varies. "Munchen" and "Rodenstock" Regula uses decimal point while GRL100 and 200 use decimal comma. Distance style is different among them in decimal number size. "Munchen" and "Rodenstock" have smallest decimal numbers, GRL100 a bit bigger while there is no difference among whole and decimal number on GRL200.

Front body metal plate design: left "Ghetaldus Munchen", middle GRL100 and right GRL200. Note the High vs Low profile of the "Ghetaldus Munchen" and GRL100 lens plate and also metal band on the front that is substituted with leatherette on GRL200.

My theory is that there was a lack of three element 2.8 Ghetaldus lenses when transitioning to or in the middle of Regula L production in Zagreb. Thus imported lenses were used. All in all Regula L with Ghetaldus lens seems to be produced in the lowest number among all Ghetaldus cameras - only approximately 2500 pieces.

Distance engraving styles: left "Ghetaldus Munchen", middle GRL100 and right GRL200.

However, since Ghetaldus isn't mentioned on the "Ghetaldus Munchen" and "Ghetaldus Rodenstock"cameras itself, I don't track these cameras' serial numbers. Still, I noted down variants I spotted during my search for Yugoslav optics equipped King cameras. As seen in the table below, there is no logical connection between properties of non Ghetaldus lens equipped variants besides the fact that all have front metal band.

Bright Frame Finder

Regula L has a variant of the reverse Galilean viewfinder called bright frame finder. Framing assist lines, shaped by the metal mask, are projected to the viewfinder with a help of an ordinary and a semi transparent mirror.

Underutilized Pronto Shutter

While fixing a Regula L, I discovered that the built in Pronto shutter has a delay mechanism that is in fact never used. Video below clearly demonstrates that slowest speed 1/30 s and B setting don't utilize the delay mechanism. However, when machined metal plate that engages shafts in the shutter when setting different shutter speeds is removed, delay mechanism is engaged and result is cca. 1/2 s exposure. However, due to removed part camera acts as it was set to B, but if shutter button isn't held down, timed exposure of 1/2 s is achieved.
Why didn't they machine the adjustment dial differently? Was camera "crippled" intentionally to not cannibalize sales of higher spec cameras? But which models were such competition? Was Cita III still being sold at the same time? Or was there more expensive GRL300 variant with Prontor-SVS shutter offering shutter speeds from 1 s to 1/500? Based on warranty cards dating I recently learned that Cita III was indeed still sold at the time Regula L was in production. However, it's not necessarily Ghetaldus tactic to hide the spec of the shutter - could be also the shutter manufacturer Gauthier. 

GRL100

Older style of Regula L body - less leatherette, more metal. Body with serial number at the film pressure plate. Bold font on the film memo dial with straight top on the number "3". Bright colored exposure counter set knob. Probably constructed mainly from metal parts. Pronto shutter. 

GRL100 on the left and GRL200 on the right.

 

GRL200

Regula L GRL200 variant

Pronto shutter, metal aperture knob. Body no longer has serial number. Dark colored exposure counter set knob. Sightly different design of the film chamber than GRL 100 and simplified viewfinder assembly. Viewfinder assembly is not screwed to the body but kept in place by plastic pin and the spring pressure when the top cover is mounted on the camera. Note on the image below that with Regulette viewfinder assembly is screwed in place again which suggests that GRL200 simplification wasn't proven successful.

GRL300

Prontor-SVS shutter with shutter speeds from 1 s to 1/300 s, plastic aperture knob. Sample needed.

 

Regula L Serial Numbers

In the table below there are all serial numbers known to me. In case there is a "*" symbol besides the Variant, the variant is an educated guess due to a lack of data.
