Al, you are 100% correct. Thanks for taking the time to find the answer. My 1st guess was Altec's. I found photos of Valencias which were similar though had visual differences from the speakers in the photo. I would never have thought to add Heathkit into my search parameters. That it took you a quick search I'm betting you had insider information!
They were at a sale I went to today, and I bought them. Amazingly clean especially considering their age. Thanks again Al!!
Tony, yes it seems the owner added the short legs. My take to the purpose was as you mentioned, to reduce the speaker's interaction with the floor.
