I've had several complete, original 1944 No.4T's without the finish "T" stamped on the left hand side of the body. I've also had several 1944 No.4T's with solid foresight blocks. Both of these are a no-no in the eye of purists and I can't vouch for 1945 production but my explanation is and always will be that there was a war on and sometimes things simply weren't done exactly as the book says.
