I am unable to find info on the wall thickness of the True Tempter AT and ATX unicrown fork blades. Don't know if they are straight guage or single butted. Anyone out there have knowledge of this?

This doesn't specifically show unicrown-type blades, but I suspect they should be similar:

I have an older Paterek manual and it does not have a tube chart in it like this. I looked on line, however my search terms must be flawed. Where did you find this?

Here is a direct PDF link to the supplemented manual. The specific chart posted in this thread is on Page 88. Which I believe is actual page number 2-65.

I have a printed copy of the 1985 edition I've had for years.

This is a link to my Flicker album of tubing companies' docs. There are a few unicrown type blades listed among the various brands. I see wall thicknesses range from 1.35 to1.2ish at the tops and some are thicker at the dropout end (likely a straight gage tube that was swaged down) and some less so (as in a single butted starting tube).

I started to scan and upload to my Flicker site bike industry catalogs I collected over the nearly 50 years of doing this stuff. I likely have about 50% more to go (when I build up motivation again, need to get really sick and have to stay at home doing "nothing") but there's a lot of interesting data for the looking here just the same.

Hey, that is real useful to me. Thank you!
