Just found this forum. Wow there's a lot of neat stuff in here. I have a feeling I'll be spending a lot of time on this site!

Need help identifying manufacture date for an Iver Johnson 5-shot .38 S&W top-break Safety Automatic; chrome; 3" barrel; hammer; double post barrel latch; single leaf hammer spring; bakelite-like hard black grips; SN M7059 stamped on left frame under the grip; 7059 stamped bottom of trigger guard; top of barrel reads - Iver Johnson Arms & Cycle Works, Fitchburg, Mass. USA; bottom of grip reads - Pat'd Apr. 6, 86. Feb. 15, 87; May 10, 87. Mar. 13,88. Pat's Pending.

Most of these features are identifiable to particular models listed around the web, except two - I can't find anything about a model with the Mar. 13, 88 patent date or with an 'M' serial number prefix. Help!
Can anyone help me determine the manufacture date of this pistol?
