ok, so I'm putting together two omega enlargers. i thought both were D-3s but are now unsure. One i bought for cheep off craigslist. the other i am building from found parts. the one i bought looks like it was modified to fit a 4x5 variable condenser head. there are homemade arms that taper in to connect to the standard 9 inch wide head but it looks like it could hold an 11 3/4 wide head. the bellows that are on it have a 6 3/8 hole for the negative carrier and the bottom where the lens board goes looks to have been shimmed in because the arms that hold the bottom of the bellows are wider than normal. Shimmed in from 7 to the 6 1/8 it is now. the column is wider than the D-3 as well. 7 3/4 as opposed to 7 1/4.
Was this an omega E series 5x7 modified to be a 4x5? or were there D series enlargers that were a little bigger to take slightly larger than 4x5 negatives?
Mystery 2. one of the parts i found is a veritable condenser head that fits 7 inch variable condenser lenses rather than the standard 6 1/2. but the distance of the arms for it to be mounted are still the standard 9 inches same the other 4x5 heads i have seen. Cant find any info on the larger size. condensers for 4x5 are 6 1/2 and ones for 5x7 are 9 inches. so what kind of odd ball condenser lens is 7 inches?
i don't have a lot of experience rebuilding enlargers, so if i say something confusing or wrong thats why.
