mark 3 serial numbers

[Raoul Duke]

About 4 years ago I came into possession of MkIII 15084 dated 4/85 (no GEQ with reverb and presence, white Tolex). Sent it straight to Petaluma for the complete service and R2 mod and have been enjoying it ever since. Mike B. was very helpful with advice and history!

Don't know if this is still active or not. I have a MKIII Blue stripe colosseum 300 serial # 22800 cant find a date, but I'm assuming its mid 80's based on the info in this article. EDIT: I found the date written in red sharpie next to the tube inputs. it reads 9/88
