Fred C, (47weewind) was kind enough to inform me that my #, 7906, belonged to;
Samuel & Beatrice Ream, 1201 Elm St., Reading, Pa. They were the first people to be assigned that number. They still lived at 1201 Elm St. in 1974, but had not yet gone on any WBCCI Caravan. By 1984, #7906 was transferred to Woody & Geri Mall, 3720 E. Orangeburg, Modesto, Ca. 95355.
however, i still don't know if my trailer has gone on any caravans. thanks for the lead. if you can find any info, we would certainly LOVE it. BTW, we do have a square "wally byam caravan" sticker below our #.
