Product timeline?

Does anyone know where I can find a complete Mesa Boogie product release timeline? I bought a brand new combo back in the mid 80's while at Berklee. I didn't have it too long though. I ended up trading in for a used Mark IIB. But I can't remember the model I owned. If I saw a picture I'd probably recognize it. I only remember it was black, had 1x12, and I'm pretty sure it didn't have a graphic eq. It was also not too expensive (as Boogies go anyway.)
Thanks, :?:

Was it an S.O.B, a Calibre 50 or Studio .22 - guess it wouldn't have been a IIC+ as you traded for a IIB right?

I'm thinking a studio .22. I wouldn't have had a lot of money then and I think that was an "entry" Boogie.

Here's a pic of a .22+. Was it like this?

I had the Calibre 50+ with graphic - it had the same front end as these amps. It was very loud, generated a lot of hiss, had okay cleans, and a super-molten-high-gain lead channel!

Yeah, that looks like it. Do you know what years its product run was and maybe how much it went for?
thanks :shock:

Mesa says that the first Studio .22+ was serial number FP 11,500 (Dec 88) and the last one was FP 28,500 (Aug 93).
