Was able to find the Blanchard (Gardiner MA) practice of adding a smith's single intial stamp appears to have likely continued with the new shops (Pacoima/Calabassas) in California. If by chance this is an inverted mark, then Lewis Wise (c.1950-70) might be the actual maker. However, I have not yet been able to find any "M" name linked with P-B, apprentice or other, so no final conclusion is drawn yet.
