xref hull and class/sail number?

I bought my DS1 about 15 years ago and have recently taken it out of storage and intend to make some further repairs, etc.
The title gives a year of 1972, but since it has mahogany seats, brass jam cleats in the coaming for the jib sheets, floatation behind the seats, a centerboard lever, no turnbuckles, etc., I'm now guessing it is really a Gen 1 boat (1957 - 1961).
When I first got it, I had to improve the structural integrity somewhat: the rudder/motor mounts and drainhole area were soggy and about to disintegrate, so I re-inforced the transom by epoxying-in a plate of aircraft/marine plywood on the interior of the transom -- and created a wider inspection port with the same material for the forward wall/bulkhead of the transom area. I also put in a wider inspection port for the bow area, removed the whatever old foam was in there, reinforced the backing for the bow eye with white oak, etc, etc.
I didn't find any plate or engraving with a hull and/or class number, but did discover a hand-written number 3632 on the starbord side in the hidden bow area. I originally assumed that was the sail number (and had it put on a new set of sails I made back then). Now I'm thinking this may have been the hull number, and the class number is probably 3-digits.
Does anyone know if there is any extant cross-reference between hull and class/sail number? Any suggestions as to what to put on the sail.
With the mahogany revarnished and a coat of paint on the inside, she is very pretty. And even though the centerboard is a little waterlogged, it hums nicely when the breeze gets her going.
