Dating an early Cook Bros; Dennis Dain can you help?

[MartyC]

One of the guys over here in Oz has picked up an early Cooks Bros frame and fork set:















Serial is 1378, so looks to be quite early and has no dropout adjusters.  Can anyone help put a rough date to this one for him?

Cheers

Marty

Hey Marty, from what I have learned in recent years and combined with my memories from the 70s I would say that frame was made in 79 (at the earliest) or the early 80s. When I was there in 78 I think they were just developing the flat brake bridge and they did not have chain tensioners yet.

As for the serial number, I was told they started over on numbers every time they changed frame design.

I will contact Claude (Masterstint) he is the Cook expert and I believe he is a member here.
