It's been too long since I've seen it, what were the details that
determined the types?

Short tail with no engine cowling raps = G
Short tail with engine cowling raps = H

OK, I was hoping for something more esoteric: G's & H's I can identify
if I can see the tail & engines.

Tall Tail = B/C/D/E/F...I can't tell these apart externally.
