I acquired an old 12 gauge double barrel Westernfield Model 327 EMJ made by Miroku Japan, The rear trigger still gets cocked and fires the left barrel, but the right trigger doesn't work. Apparently when you open the breech and close it after loading the action doesn't cock the right barrel any longer. Since this old side by side was imported by Montgomery Wards from Miroku back in the early 70's can spare parts to repair it even available today? And if not are their gunsmiths who can replicate any broken parts within the shotgun to repair it? Thank you.

Sounds like a Miroku Model 500 or a derivative thereof. I've used a gun named Louis Rotelli, a gunsmith in Gaylordsville, CT to do some repairs and was quite satisfied. 203 788 4920. Best to call after 5:00 PM Eastern time.
