BEWARE of this listing https://www.ebay.com/itm/selling-rare-pre-war-colt-22-ace-conversion-kit-with-original-box-used/303119843759?hash=item469359c1af:g:hToAAOSwYipcqiQP The listing party has listed this as a Pre War .22 conversion Kit. It is not. Were it pre war it would have a serial. Were it an early post war it would be serialed. It is not. Seller doesn't accept returns so if you buy it you will not have what it is advertised to be. You will have a post war kit only. If you have already bid then withdraw your bid as the listing is lying about the item for sale. If you have already bid too high and might win, I would refuse to pay. Prior to 12 hours you can withdraw your bid.
