    These are two nicely made pinholes. I measured them and as near as I can tell, one is .38mm and the other .40mm. I looked online and the ideal focal length for the .38mm is 72mm and for the .40mm is 81mm. I see that the metal is not completely flat, but assume it can be flattened.

    $10 for the pair plus 2.00 for US postage, $5 for overseas.

    I would guess the slight bow to the brass is so it will spring when pushed into a holder slot.

    sold.

    I believe these are somewhere around 100 years old.
