....The first appears to be an inner tube repair clamp shoe used in conjunction with a heater to set a (1 1/4") patch.
The second is quite interesting in that the hand tooling seems to have been done BEFORE the keyhole voids were made!?
Question.....appx thickness and type of material (looks quite thin and copper).
Good pics !
EDIT.... Failed to find a good example of an inner tube repair part like this. M.
Vhoov , any chance on one more picture of the bottom (opposite) side of the thing with the stud ?
