What code is my 21D?

[Squid]

I tried to get some good close-up photos of the mixer pin area, but neither my phone nor the Nikon was cooperating...I'll try again later. It does look to have a bit of a countersink to it, though. Thus far, I've not gotten too bogged down in with small variations. Instead, I stick with variations that even a casual observer would notice.

Squid, how long have you been a member here? I bought several cars from you back in the late 90s but then your page disappeared. I assume you are the same Squid.
