DURST LABORATOR Negative masks

milos88 · Nov 25, 2020

Hello,

I bought a bunch of negative masks form a surplus store, thinking the are DURST Laborator 1200 masks, but it turns out that
the ones that go into the Femoneg film carrier have cut off corners and mine don't.
Below are images of the masks. They come in two parts, one top and one bottom mask, and the top one has an Anti Newton glass. The size is 138x138mm.
Can someone please help me identify them?
Thanks!

They look like for Durst 138

That is what I thought, but the size is the same like Femomask, maybe 1mm difference on each side. Shouldn't the 138 mask be large enough to accommodate a 13x18format (5X7)? I have all asks from 24x36 up to 4x5"

Well, LAPFE masks look different, had no glass, and have LAPFE clearly written on them too, so I suppose not standard LAPFE type I was thinking off at first.

Could be for the Laborator 1000?

My L1000 is in storage just now while I use the L1200.

They look third party/ custom made - Durst masks tend to have identifying acronyms/ names/ numbers on them. Possibly Kienzle or someone like that made them? Quite a few outfits made specialist inserts over the years for odd formats with AN top glass.

Could they be Devere?

They don't really look like most of the factory De Vere masks to me, but KHB Photographix (for example) has made aftermarket masks with AN top glasses.

Yes they look like the ones on KHB but for AN glass glued in. The glued in part makes me think DIY. or like this

De Vere mask inserts are 125x155mm (measured them) - and the pin shapes on the OP's masks don't match up with the De Vere ones - furthermore, the bevels on the edges would be the wrong way up if the top plate had simply been turned over to use the recess to accommodate the AN glass.

@milos88 which country were these acquired in? They're likely either for a Durst or something that uses close to Durst insert dimensions - Kienzle?

Thanks everyone for pitching in! They were bought in Germany, and were in the same box with one FEMOGLA AN glass for Femomask, the one with cut corners, so I assumed they were for the same enlarger. I am planning on getting a 1200 Laborator in very near future The masks are square, all sides are the same size, 138x138mm. The Femogla is 139mm. I do not have the negative carrier Femoneg to try them out, but I got alarmed when I looked online, searching for an enlarger,
and saw Femomasks that have cut corners , so I got alarmed that I may have something that will not fit while I was sure that I gad the masks covered.I did not plan to buy these in advance, it just happened, and I know I should have first acquired the enlarger, but these things are rather difficult to come by, so I thought I'd get them better than be sorry.
I looked at some of the links posted here, and I must say again, my masks are SQUARE, not rectangular.
Can anyone who has a Laborator 1200 tell me the following:
A. Would a square 138x138 mask fit in place of the FEMOGLA which is 139x139mm, and would that 1mm difference make a problem?
B. Would a square mask above fit in a negative carrier that usually accepts square masks with cut off corners?

Thanks again!

I'd drop an email to Kienzle - they offer many neg carrier inserts for all sorts of enlargers & may well have made them for their own C120 enlarger.
