is no longer listed as one of the Cowboy Action Revolvers on his conversions list. The Texas Ranger is listed so if I remember correctly the Arizona Ranger was a series that was limited to the guns he converted at that time. He is at the Handgun Hunters Challenge in Monterey Tennessee and will be back on Monday so I would expect if you resubmit your question next Tuesday or Wednesday he will be able to respond to your question. I have seen some of the current prices on conversions so I would expect a new conversion to cost in the neighborhood of $1700 to $2000+ depending upon the features (engraving, action job, special grips etc.) so if I were you I would hang on to that gun with both hands! Besides being a work of art it will be one of the most reliable guns you can ever own. Besides, IT WAS YOUR DADS!!!
