Federal Stow Away 6X9 enlarger

I have an old Federal Stow Away Jr. 6X9 enlarger with a doublet uncoated lens, attached is a sample, low res scan. The negative is 6X9 taken with Mamyia Universal 100mm 3.5 film is ultra fine 400 extreme, developed in D76 1:2, printed on Multitone with 2.5 filter. The Stow Away is made with stamped parts, cone rather than a bellows for focusing, water house stops, it is light tight and comes a glass negative carrier. The only change I've made is that I swapped out a LED blub for the clear incandescent that it came with. For a 60 to 70 year old enlarger with a really basic lens it does rather well. My only real complaint is that the 6X9 negatives need to cut into singles. I plan on reprinting with Foma fiber grade 3 and develop in a higher contrast developer maybe do so bleaching.
