Ok thanks Wayne! Yes, I just found the keytop/keylever assy part numbers pages on the navy site. I had no idea there were SO many different combinations of LC/UP keytops. I will be inquiring with Paul about.these now that I have p/n.
If you have no luck on GK you can go to Paul Cembura. He has a lot of 28 stuff. He does have a $20 minimum order so I suppose you could get some paper tape or whatever.
