Box and Pan Finger Brake nose pieces Part Pexto DiArco Berkroy National Chicago

Description

This is a box and pan brake finger that I got in a box of parts.  It is 4 and 3/8" long and 1 1/4" wide and 1 1/4" tall.   I tried to draw it with dimensions, but picture did not come out real clear.  I thought it was a Pexto, but could not find anything on it or a DiArco, Berkroy, Beniot, Jet, National, Cincinnati, Tennsmith or Chicago. It has been dress a little, but no damage to lip and the threaded hole in top has good smooth threads. Weighs 1 pound. If you need any more information or you know what brake this fits, please email me. Thanks.
