We are proud to offer a WHEEL LOCK pistol. See prototype pic. attached. Our prototype actually had a stronger mechanism than we had hoped for. This was a great relief to us, for as most of you know, this form of lock mechanism is delicate and is a rather high maintenance item. Details will soon be posted on our web site. We are now accepting orders for these magnificant pieces of machinery so please inquire for price and delivery ETA.
