In reply to my own earlier post which contained a disparaging comment about The Rifle Shoppe in Oklahoma, I have to retract my disparagement!
I just received my assembled wheel lock with spanner today, a good two to four weeks ahead of what they estimated! The lock is a massive hunk of steel (with a cast brass wheel cover), weighing a whopping 1.4 pounds by my scale! Appears to be very well built, though I can't comment on sparking power, since it was sent with an oversized flint in the jaws, rather than a pyrite. It obviously hadn't been spark-tested, since the big flint doesn't contact the wheel, and shouldn't be used on a wheellock anyway. So anyway, my apologies and thanks to The Rifle Shoppe! Now the search is on for pyrites!
