<HTML>Alan. How old does it look?    If it is of  recent vintage, it could be a C.   The C , sold as a "classic" , was 5'7" or 5'8".   It would say Classic on the bottom right corner of the fallboard.  If it is older, it could be an E, H, or G.  I'm not sure of specifics, but know I have seen these models in that general size class.  Many Baldwins have a letter cast into the plate on the bass side of the tail.  You could look for that.
