IBM Selectric 1 spherical double shot PEI, smooth!

They look so thick and feel so smooth and shiny!

Polyerithermide keycaps are op

Why are they not on keyboards today? Or perhaps PBT is superior in terms of wear mechanics and strength?

Really need a beam spring keyboard to give them a second Life

I use a Selectric every day at work for typing out envelopes and carbon copies. The machine has been in daily use on the same desk since the 1960s. Our caps are in similar shape, but we have icon mods instead of text mods (both grey with white legends). Yours grey seems a bit brighter.

Are they really double shot PBT? Have you done the acetone test? It should not harm PBT at all while melting ABS and other lesser plastics.

I'm skeptical. The technology for doubleshot PBT was only done recently, IIRC.

I'm quite surprised that the abs being out there for more than 5 decades has survived not yellowing for that long. The letters are whiter than my IBM model F caps and even more so than the kkk 

These are beam spring compatible right?

That IBM looks exactly like one of my mother's old friends. God that takes me back.

Don't think they are.

Quite sure they are beam spring compatible tbh. The selectric 1 and 2 are cross compatible and the beam springs seem to accept the same kind of vertical stem profile... Can anyone confirm? They even use keycaps that seem to be the same as the ones on the selectrics.
