Understanding Markings on Hamburg Steinway String Frame (plate)

    I am assisting in the partial rebuild of a Hamburg Steinway model B from 1968. At the tail end of the string frame (AKA "plate"), there are some numbers that are cast in, and then some numbers that were hand-written on. The hand-written numbers are "1045". (The numbers cast into the string frame are "1636" and "67".)

    The bass strings will be made by Mapes. Mapes has advised that Hamburg has had a few different bass string scales over the past several decades. We sent them a pattern, etc., but were wondering if the numbers at the tail of the "plate" were an indication of the specific string scale. Any one have a clue?

    Thanks,

    Alan
