Yep, those are mine. It's not that I can't fix them, it's just that I've been running out of time to get personal projects done so I've been selling more things non-refurbished other than doing some of the more prohibitive parts like installing the xWhatsit controllers for those that don't have a lot of soldering experience. The 3178's here have the absolute best foam that I've ever seen on model F's, I believe because they were factory repaired at some point as some have IBM repair stickers inside, and the foam type for replacement was much better than the originally used foam. Seems like craft foam actually.
Since the foam definitely will not have to be replaced, it will be as simple as removing all of the keys (except space bar, which has the stabilizer on the underside of the board that holds it in), then prying up the tab that holds barrel plate and backplate together, then sliding it apart. Just a wipe of the flippers and PCB with isopropyl alcohol and you should be good to go and assemble in reverse order! Barrels can also be taken out and cleaned along with the keycaps if desired.
This whole process should take less than 30 minutes to disassemble, then it's just a matter of deciding whether to soak the barrels and whether you want to wire brush and paint the top barrel plate. I figure it will need to be disassembled anyway if you want to do those things, so there's not much point of me doing it if it's going to need to be disassembled again for full restoration.
The 3178's use XT style barrels, so if you are looking for spares for something like the Xtant project at a good price, the $54.44 one without controller (which would be $49 shipped with my 10% discount described below) might be a good option for someone since XT's seem to be going for much more than that lately.
Also, note that ALL of my ebay items qualify for a 10% discount if you message me through here and pay by direct PayPal invoice INSTEAD of buying through ebay since this saves me fees, which allows me to pass those savings onto you. Furthermore, I will give a $5 discount per keyboard purchased if you buy multiple keyboards at the same time. All of my keyboard related listings can be found here:
