XT keyboards (and missing decal)

Hi all, I've got a 5160 here with the XT keyboard - however it's got the 64/256K motherboard fitted (with the "early" Jan '86 EPROMs), and Wikipedia seems to claim that by the time the 64/256K boards came out the machines were shipped with 102-key keyboards (the XT flavor of the Model M, I assume). Anyone know if that's true, and so my system should technically have a "full size" keyboard, or was there a crossover period where systems with the newer boards shipped with the 83-key XT keyboards? Everything else about the machine suggests it was built sometime '86 (dates on the PSU, IC date codes on the expansion boards etc.), although it has a 20MB F/H IBM hard drive (rather than the H/H Seagates that I think the newer systems got). There's no ID info on the underside of the keyboard like there is on my Model M; I'm not sure if there should be. Also, I'm missing the silver keyboard decal - I believe these just said "IBM personal computer" like they did for the 5150, even though the 5160 case decal mentions XT. Does anyone have one they could pull from an otherwise-junk keyboard that they might be willing to part with? cheers Jules
