Hello,
Welcome from Ontario.
You have a very nice looking .455 2nd Model there. These revolvers are frequently seen up here. Most of the ones I've had a look at have not been converted. I believe I saw your for sale post a month or so ago on CGN. For some unknown reason (to me anyways), they don't seem to be very popular up here. I've seen several in similar condition as yours in the $800 +/- range and not sell.
