Thanks for offering this item at such a good price. Proved handy in identifying the part I was looking for my set.
Thanks again.

This is the original manufacturers service manual, with detailed info on the circit boards, explosion drawings of all parts in assembly order, and tuning instructions. The only thing missing is the information on the dimensions of the various drive belts. mail me if you need them. gcrossman_at_aol.com
