eBay and Craigslist finds

It's a steel frame , in the right hands it could get straightened out, the dent will always be there.
You could try and make a cheeky offer.
One of the 'lads' at colour tech (Ron Cooper or Barry Witcomb) could straighten that out.

Probably.

I can cope with the dent, but that alignment is an issue.
I'll see what he says, but on eBay he could probably shift it (I expected it to go way past £130) as is, so he might not listen to a cheeky offer.

As you say, it is steel, so could be bent back. I'm just not sure if it'll have fucked the welds as it's fillet brazed.
