"What's this pipework taken from the lower photo"

The only large diameter pipe on that side is likely to be the steam supply to the left hand injector but given the more advanced state of disassembly shown on the lower photo it's possible that the pipe is not in its original position. This is where a Pipe and Rod Arrangement drawing would have come in handy.
After further consideration and given that it could be attached to a fitting on the side of the Tank this could be a water gauge for indicating the water level?

"Taken from the the top photo, I assume the item outlined in read is the westie, but can you identify the item attached to the backhead and the pipework attached to the tank side, both circled in green?"

The item outlined in red is the Drivers Brake Valve and nearby should be the B.V. Isolating Cock and a Release Valve. I can't see a West Highland Terrier anywhere.
Rob has already correctly identified the Gauge Glass, minus its protective glass cover. It's unfortunate that the small diameter pipe had been disconnected so we can't see where it originated from but given its proximity to the Drivers Brake Valve this may be the feed to the Brake Valve Reservoir, possibly located in the box at the rear of the water tank. This is pure speculation and I can't see anything on the General Arrangement to confirm it.
The GA for the Class O shows a small tank in exactly this position!

Amended to include further information shown in red.

Handle seems a bit low. Wouldn’t a hand get trapped?

 

Are we talking about the same thing, I mean the handle on the wheel. Not much space between the handle and the tank

 

We got there in the end. Have to say I am in awe of your drawings.

 

I’ve seen his signal box and I’m in awe of that as well.

 

The Class A backhead will be similar to but not necessarily identical to that of the Class C. All I can offer is this extract from the layout diagram from the NER instruction book. There are plenty of images on Google of the Westinghouse brake valve that would help.



Yes, the lever marked in red is the brake valve. I'm not sure what the valve indicated in green is but there is no indication on the crash photos of a similar fitting on the Class A.

The reverser cover does not protrude beyond the back of the tank and is shaped so that it's vertically in line. This results in the four bolts on the bottom of the cover being spaced closer together to compensate. In between the two lines of bolts is an indicator showing the amount of cut off.
