I have a few AF cast clockwork engines like the AF10. Somehow I lost the one windup key I had during my move. I've tried Ebay, Facebook AF and clockwork groups and online trying to find a replacement key with no luck. On Ebay looked at buying another engine to get a key. Problem is most engines that have a key are over $100. Tried various coupling nuts at hardware stores, but none have the correct thread. Any help of finding a correct key or maybe someone willing to part with one? Thanks.
