I purchased this 5x14 NOB Leedy "Professional" model (circa 1927-1929-ish) probably about 6-7 years ago from an antique store in Sarasota, FL. I dismantled it, hand polished every part, then carefully labeled everything, wrapped them up and stowed it all away until I felt I had time to deal with the totally rusted, slotted tension rods. I finally got around to getting them re-plated recently and she's got a new lease on life. The only non-original item was a new rivet on the Speedway strainer that I had a machinist replace.
The back story from the antique store was that the drum and a few other items were found in a backroom closet in the Sarasota Municipal Auditorium (built in 1938).
