Thanks. I must have been thinking of Optimus. Was Primus a Beck name - since you have VM available?
-- Ole Tjugen, Luddite Elitist
Looks like Primus Beck was a trade name only and not a part of the company name R & J Beck
just got one...
But I don't know anything about it. The VM doesn't mention a lot (just "several"), and the one description is dated much later than this one must be, as the Jamin name is written on it.
Original case - "secret" compartment in the lid where the original flange and a front plate was hiding..
Compleate as I can tell.
on the lens is written "B" and "PORTRAIT" - on the base of the barrel it says "A".
I am almost sure the Portrait "mode" is a petzval...
6 extra lenses to combine - 8 waterhouse stops.
Anybody know about this kind of set?
Wow! That's the sweetest casket set I've ever seen bar none! Does the piece that says portrait effectively lengthen the barrel, ie. when it's in Portrait (petzval) mode, it has that piece to make the barrel longer, and when it's in regular mode with some of the aplanat components, the barrel is shorter?

just checked, and yes, the markings "Portrait" is actually a part of the petzval parts - and that makes the portrait longer than in "landscape" mode...
the 5 cells (beautifully made!!) have numbers on them:
the sixth one looke slightly different - has no numbers, and looks like a cell to be put at the back of the barrel (?)
8 watehouse stops with the numbers:
2-5-6-7-12-15-18-29 (maybe millimeters? the biggest numbers has the biggest hole)
I have 3 casket sets, two of which will cover 4x5 and 5x7. The third is a puzzler. No brand name, bayonet mount, waterhouse stops (has a complete set in the original purple-leather-lined case!), and 6 elements. I am having a flange made for it right now so have not been able to test it. I do know that the barrel is labeled No 6 which I hope means it will cover 8x10, as my other sets are No 3. Each element is paired with a sleeve numbered 2,3,4, and 5. Numbers 6 and 7 have no sleeve and appear to be for the back of the lens since they are gunmetal grey and the other parts are shiny brass. They are nearly 6cm in diameter, so quite large, and no indication of focal length. Of course no instructions.
Anyone care to speculate? And does anyone think it may cover 8x10?
I have two, er, three sets. The first is a Dr. Staeble Polyplast with all elements in a dial-set Compur; great set. The second is a 13x18 Meyer Euryplan VI in a Compur; also a great lens. It came with three out of the four elements; fortunately I had another Euryplan element of the required focal length. The third is a set I cobbled together in the mid 1980s from assorted (eight) B&L RR elements mounted in an Unicum; it covers 9x12 and 13x18; it actually works quite well as all of the elements are extremely clean. I also have some w.w. cells for it and also a Gundlach Pancratic that fits into the shutter. All in all, quite the Satz! Alas, I have not worked out all the focal lengths and f numbers with extreme precision, but all in time, all in time.
