Ask here : GT Museum . I think it's best GT connoisseur...
Yes, this can help for sure.. But round end cap sounds overseas build...Presume the serial number might help. I'll post it up once home.
It's definitely not a US made frame. These've a digit only serial number. RTS 3...Serial no is GT7004T96 ? Doesnt look like any other ones I find on google.
