Clamp identification

[Gary]

I’m being a bit slow today but what type of clamps are these?

I’m after some but would ideally like the flat bar to be a round bar 8-10mm in diameter.

They are ' table edge clamps ' as far as I know. Mainly for clamping plywood to the edge of a table and using a fretsaw. A bit old school now.

Very similar to the clamps that come with the vintage knitting machines !
Not sure about the cut-out on the corners though.
Havent seen any with round bar. Nearest thing would be fence clamps:

They do look a bit "recent" but they are identical to fretsaw table clamps. The metal table had a slot to take the clamp and the table (with a vee-shape cutout) was clamped to table/bench and hung clear to enable fretwork. Mind you I have seen similar clamps holding up ping-pong nets!

fret saw clamps; available on the big river company site and probably on eBay too.

I have a few of different sizes and very useful to have a times.
