Gentlemen, I've been cleaning up a flock of A-11 aircraft clocks of various makes but I'm stuck finishing a Bulova model. Bulova called it the 21AE, it's a pretty standard 2" aircraft clock. I've managed to find all the needed parts except for two, the third wheel (Bulova B-5) and the center seconds wheel (Bulova B-91), part numbers are per the official handbook. Can anyone offer a hand? Not looking for freebies, I'm willing to buy them, but Bulova parts are very hard to come by! Thanks in advance!
