Help identifying bike

[sawspud]

Can anyone help me with identifying this bike? Other than the Dura-Ace AX components there are no other clues that I'm aware of. The downtube seems to have an interesting profile for an old frame.

I've not seen the bike other than in the pictures, but if you need any more information I can try and get hold of it.

Thank you in advance!

It's from the aero revolution period at the beginning of the 1980s. I've seen the down tube and bb on a number of Japanese bikes from the period - Koga/Araya etc, I'm fairly certain the tubing was Tange although something is telling me that Ishiwata made a similar section tubing set. Think that one company set had an aero section seat tube while the other didn't.

Thank you Jim. The owner is looking to sell - I'm going to try and talk him into not selling the parts individually! With a little TLC I would imagine it could look like new. I'll make sure he takes the bottle cage off though!

The correct bottle and cage is here on VeloBase
as a unit they're usually quite expensive though there is a cage currently on Ebay for £8
