I’m restoring an IBM model F-122 and I want to update the wire-stabilized keycaps and use the barrel inserts instead. Don’t want to have to deal with broken stabilizer clips on the plate, etc.
I’m looking to buy the following replacement second gen keycaps:
backspace
iso return
long shift
numpad zero
numpad enter
I really want the legends to match too. Can someone hook me up?
Also, is it possible to know by date, which model M boards would have the barrel insert style caps?
Attached image shows the legends I’m after. Thanks for any help!

I don't think that you will find any of these, with the exception of the numpad Enter.
From personal experience, and I have only a few dozen to go by, the symbol markings are only found on the earliest terminals.
Only a very very few of the earliest Model Ms had wire stabilizers on any key but space bar, and M wires are much heavier gauge than F wires anyway.

Nah, I've seen them on Model M-122 boards for sure. I'm just unsure if they are the wire stabilized versions of the keycaps. Sounds like probably not?

You'd probably be able to find an early M122 with similar legend quality, but they will probably have a wire under Numpad Enter. Like Fohat said, the M's wires are much thicker and are not compatible with Fs. This is especially a problem for the spacebar.
I think they stopped the wires in mid 1987, but I could be completely wrong.
I'm in the process of ordering a custom set from Unicomp for my F127, but I'm well-aware that I'm going to have to epoxy the stabiliser holes on the spacebar, so that the F wire fits.

ISO versions of the standard model M also sometimes have these legends, at least according to my Googling. The wire is irrelevant, with the exception of the spacebar. They just need to have the stem that goes into the insert. Found some more images of M122s with the caps off and they definitely have the barrel inserts, so they do exist.

Easier: shrink wrap on the thinner wire
