Hello, I found these this morning at the flea, bit cold there, 4 degrees outside air temp., didn't feel much warmer inside. They are stamped Braunsdorf Mueller Co Eliz NJ 10. I looked at AA, they show a number 7 (1/2"), and a Number 9 (5/8" ) . These are are 6 point, and measure 11/16 " across the flats, same size, both ends.There is a hole for a bar in each. The original box reads 1/2 doz. 10 size (the 1/2 and 10 were hand written). Could these have been a special order? Regards, Lou
