I have a pair of w/o belles in need of a new home. The letter 'J' is stamped on the back, 1971 I think. Tag only on the back of one speaker with serial 8561373. The veneer looks to match on both but I cannot say they are consecutive numbers. I can find no chips, scratches or dings on either. Bought them several years ago from a forum member. They are all original. I am downsizing and they need a new home or to go into storage. I am pricing them at $1500. I am in eastern nc 6 miles off of I-95 and 10 miles off of I-40. Now, let's see if I can get pics on here. May take a while.
