Can't find the HIN

[Yorkman]

I have a 1973, 21 ft., Holiday. I can't find a Hull number on the transom. Is there another place to look?

Could have been a 1973 model, but built before November 1, 1972, then it wouldn't have a HIN.

Otherwise, top starboard corner of the transom. No secondary location back then..
