Nope...that looks like an Acme/Ilex something or other shutter, probably with a Paragon or similar lens, or some nice vintage Kodak product..principle is the same though...I like the idea of the 6x12 Holga with an LF lens by the way (and off topic). Doesn't have to be 'blad, there is plenty of other glass out there just as good or even better (ok, 38mm Biogon aside perhaps

)....At the same token, there are quite a few cheap lenses ala Holga that would fit a 'blad. Just remember the shutter issues...No big deal come to think of it.....I'm thinking 75mm f1.9 Oscillo-Raptar in shutter....

....They're crazy/weird/crap lenses in good shutters and are usu. as cheap as/cheaper than a Holga....Just glue them onto an old Hasselblad Body-cap that you've reamed out to the right size. Focussing? Claro: Glue a (painted flat black if you must) PVC tube on same and let the lens slide in/out...end of story. Enjoy!
