What I can make out on the front fork drop outs is TANGE TP. The rears are SHIMANO with axle position adjustment screws. The Dura Ace date codes are as follows:
Crank PB = 91 Feb
Headset NS = 89, it has an S for the month so I am not sure about this date code
Brakes FB = 81 Feb
The derailer is a RD-7400, I haven't been able to locate the date code.
It seems the brakes are the oldest style item on the bike so I think 81 should be close to date of manufacter. It looks like I have a bike with a mis mash of parts. All the parts are good but this certainly is not adding up to a pure vintage bike. I removed the blue paint on the chrome forks and they look great. I tested a spot on the bottom bracket and it appears there is only this one coat of dark blue paint.
