Does anyone know when TTT stopped making bars under their old name Ambrosio and adopted the TTT trademark? I thought this occurred in the very early 70's, but I just bought these bars on eBay from a list member:
He was told, but has not been able to verify, that these are late 70's or 80's. The style could fit in that era, but I thought Ambrosio bars were long gone by 1980. Did TTT make bars under both names for a number of years?
