What, we can't say Matsu****a?

Well, I guess the moderators need some some of auto-censoring to keep the trash out of the forum. Obviously, I'm a trash type.

Talk about your irony. I just tried to add a sarcasm emoticon to the above paragraph and it's not working!

Thanks T-Mar. I googled Bridgestone bicycles and they look very much similar to the frame I have.

T-mar, do you have a database handy or do you have all formats for serial numbers memorized? :)

I have no reason to doubt that it's a Bridgestone. It's definitely not a Univega. It's a mid-level frame with the way the rear stays are joined to the dropouts. It's got something like ishiwata hi-ten rear stays and Ishiwata cromo main tubes. It should be a good rider whatever it is.

Appears to be mid 80s Bridgestone with Ishiwata triple-butted Cr-Mo tubings.

Both. I'm a long time member and have started numerous threads to analyze the serial number formats of several major brands. The resulting databases have led to the decryption of serial numbers for many brands including, but not limited to, Bianchi, Bridgestone, CCM, Centurion, Fuji, Miyata and Nishiki. Some of the threads have become quite large (the Centurion thread is well over a 1000 posts and several hundred pieces of data). When you've worked that closely with that many pieces of data, the formats become ingrained and easily recognizeable, so most of them have involuntarily been committed to memory.
