The TC hatch has a built up block on the outside, right side of the hinge that prevents the hatch from opening any further. It's molded on to HL and Tamiya hatches and is the same hatch on the E8 Sherman. It locks open and there is a small spring loaded pull ring at the bottom inside of the hatch to release the latch to close it. Monday, I'll make a point to get a photo. I have to clean up the inside of one of our Pershings Monday and reasemble what I took apart Friday.

Harq, the breechblock is down and firmly rusted in place. I have been trying to close it, but need an rammer-extractor tool to trip both extractors together. It full of dried grease, paint flakes and rust. Normally I'd push the breech handle down and trip them with my hand, letting the block up easy, but with so much crud and rust holding it....no thanks.[:@] I'm an oboist and need my fingers.
