Frosty, R&J Enterprises carries them. They're good people to deal with too.

I'd call them and talk to Joy to see what the status is on them. Their number is on the website.
If they don't have one is stock they'll get it for you. They're in Washington St. right near the guy that makes them. I would think a 2 in Hold & Fold would be fine for your 1/72 stuff. The main thing it'll come in handy for is fenders. I don't think your fender sections would be more than 2 in's long.
I've also found the Xuron Tweezer Nose Pliars to be invaluble in my Tiger build. They have a flat ground nose and straight sides all percision ground. Great for doing the small stuff by hand. You can check them out here but see if you can find them cheaper somewhere.

Looking forward to seeing more of your itty bitty tanks!
