PDH, Interesting, as I have a Federal 279 which I think is similar to the 288
except it has the optional condensor module at the bottom of the lamp house
I think there there are not many Federal enlargers still in use.
We know now, at least 2 !
I put on an LTM M39 thread (using a plastic Rodenstock lens box) on so I can use newer lenses.
- Rodenstock 50mm and 90mm
The enlarger came with a 6x9 holder with a set of aluminum glassless, and a glass holder.
I modified a 35mm slide holder from another enlarger to fit in the 6x9,
and mount the 35mm negs in Gepe slide holders.
I have the instruction manual which covers models 269, 269CL and 279
and has an exploded view parts list.
Also there is an order form for parts and accessories for all the above models plus the 288.
The only problem I have is that the negatives tend to overheat during set up of easel and focussing.
Notwithstanding that, I have made some very pleasing family portait prints on 8x10 Ilford Multigrade pearl.
