Eddie can help if he brings us the important info, especially its serial number. I can tell a lot from that.
2holer, Eddie reported it was marked Long Range. Is your Ward gun so marked? Kutter, I have never tried to fit one to the other but, other then the trigger tang inlet on the nitro, might well be interchangeable. I will visually compare the WA and M-6 Lefever A-grade .410s I have and post later.
I was in the old Knick room (custom shop) some years back and Art Twarz was checkering a straight grip that had been fit to a Nitro in a very similar pattern as the question gun.
