Marin team titanium serial number

[stocko]

I've just collected this team titanium frameset from an old cycling friend of mine and need help with the serial number as i can't find any info...

Number on bb is 6642 i believe

** Also anyone know correct seatpost size for this...xt post is 26.6mm but seems a little too loose**

A Marin Team Titanium Litespeed made frame 89 to 93 should typically have a 4 number Serial located on the right Dropout. Not sure what model year your frame is from? Someone else on here may know. But 6642 is a higher serial number than my own 93 model year Team Titanium. Your frame also seemly has later design post 93 Dropouts? Others on here can likely confirm this. Possibly they been replaced? Nice frame regardless.
