Help ID TBTC jersey - Beavers?

[topekabob]

Greetings Friends! If anybody can shed some light on the TBTC jersey pictured here I would be very thankful. I bought it from someone in Portland, Oregon along with a TBTC Portland Mavericks jersey, worn by the Portland Rockies in 1997, so my suspicions are that it was worn also by the Rockies to honor a former Portland team. One would think the Portland Beavers, but I can't seem to find any Beaver photos that match this style of jersey. I called Ebbets Field Flannels and they tried but couldn't find anyone at the company who knew what they had made it for! They did say the tag was over ten years old. If anyone can ID this logo and jersey I would appreciate it!
