ANTIQUE UNUSUAL DRAFTING TOOL ORIGINAL CASE $61U.S.
We're offering for sale this unusual tool in it's original case. I don't know what it was used for , but am assuming it is used for drafting, since it came with other drafting related items. It seems to be all complete with 5 extra "gears" each of which is unique as far as their "teeth" are concerned. If you can provide additional information, we would appreciate your taking the time to do so. The instrument itself is stamped with some sort of maker's logo mark. The case measures 3 3/16" x 2 9/16".
