1990 Diamondback Ascent Tubing I.D. svp

[BiketoBasics]

I've got a 1990 version, just the frame & fork (curved, not straight) though and not the EX model. The frame had been repainted some kind of appliance white. Carefully scraping off the paint reveals a few of the frame decals underneath. It was designed in USA, made in Taiwan. 100% Cromo MTN tubing reads the other decal. But, there are no other decals in places there should be. It would be nice to confirm the manufacturer of this tubing though with another member of this forum. I've decided to try and repaint it hopefully before winter shows up. Hiring out for the job is proving expensive and probably not worth it for this frame.

Could it be True Temper?

Uknown, Old Fisher. Records indicate Diamondback did use TT tubing but whether or not this one is Tange or TT is yet to be determined.

I found this thread which goes into it >>> https://www.retrobike.co.uk/threads/1990-diamondback-ascent-finished-19-12.124880/
chrisv40 states that his 91 model is TT tubing, but that is a 91 and not 90.

Mine has the same paint job as seen in that thread >>> photo
