Thank you, found it. Also, found the serial number after a lot of scrubbing. How can this thing be that old. It's number is 5016-12. I looked twice actually. I pulled up the website and looked again. Yep, it was built before 1937. So, I guess I now know, I have the old head design. Was curious about that. I really wish I had the drive lugs, but I don't, so I will have to make do.
