Trying to see if I’m right on this one. Looks like 1971 to me. Serial number starts off 671 and the home is 1971. The data plate is also up top which I believe hasn’t been done in a long time. Amazing condition if it is.
I just thought it was funny to start off 671 and not 0671. 2 plus 2 still equals 4 though. Thank you.
Correct me if I am wrong, but it looks like the relief line runs upward off the TPR valve. That would be the middle pipe.
