I need a little help to find out what brand this frame is. Components info:
- Complete Shimano Dura-ace black first gen (GA-200) except front and rear hub from Campagnolo.
- Wheels are old Weinmanns.
- Seat post from Selle Italia.
- Handlebar from 3T cycling.
Other relevant info:
- The original colour is a sort of metal red (dark). It is apparent on some pictures below.
- I found two engraved numbers on the frame that don't look like any other serial number I've seen before. One at the top of the seat tube (323) and one under the bottom bracket shell (Z100).
Thanks in advance for any help you can offer!!
