Re: Topbow thumbscrew
Can't say for sure in this case but the early thumbscrews I believe were coarse thread (or was it visa versa?) Anyhow either way, they did come in both thread one for early and the other late. Where that change took place I cannot remember but someone will chime in here I am sure.
Now as for the possibility of a smaller thumbscrew altogether, I have come across smaller ones as well and always wondered what they were for. I had originally thought that someone had them re-cast as repro and they shrunk because they didn't allow for the cooling process.
This is a good question. What were the smaller thumb screws created for?

Can't see your pic, but the EARLY ones were 5/16" NF (A-2901) and the LATE ones were 3/8" NF (A-3719).
