Nice collection and love the Gerstner too.
Thank you. She filled up fast! LOL. I just recently bought an O-42 that was likely assembled in the 80's (so not super old, but still shows use). I just ordered some new hardware, felt, and finish/cleaner for it. Hoping it's a fun project. It's a bit smaller than the O-52 pictured, but it's a darker color and I think will look super. Maybe the fixed blades will live in that one assuming I get the restoration / clean-up done successfully. Fun stuff.
