I was cleaning up my stash and found a NIP Great Planes/Tower #OSMG3642 or OS# 21481700 drawbar style carb retainer. Fits 10A, 10E and some FS carbs... Tower price is a ridiculous $6.79.
It was shipped to me in error and Tower did not want to pay postage to bet it back....
Need one?? First contact gets it for the price of a SASE........
