Years ago when I was a younger man I could shoot my D/W with iron sights. Now I'm taking the gun out of the safe after 30 years of non use and find I can't see the iron sights well enough to shoot accurately.I'd like to use a 2 or 4X Leupold but don't know where to find bases for this gun that in no longer made. HELP!!!!!! OLD STEEL SHOOTER Frank

Check out gunbroker.com.

i have one that was never used,if you are interested i will go and find it and see what brand it is.

I just did a search for clamp on bases and B-Square came up. Must still be available.
