60mm mortar build
has anyone done a 60mm mortar build? I am being told there is no protrusion gage for the firing pin. So my question is does anyone have the specs on a brand new pin?

Damn Ossifers! The M19 is a 60mm. (81s didn't have lever fire.  )

Thigh saddle???
Any former 11B-S and most 18Bs know the M1 base plate is not a "thigh saddle"
"The 60mm M19 could be used as a direct fire weapon by attaching the small M1 base plate to the barrel. This reduced the mortar weight substantially, and greatly lowered the weapon profile in the open during fluid engagements. The idea for this weapon originated in the deadly Japanese "knee mortar" of WWII. (It wasn't fired from the knee. Doing that would break your leg.)"
I'm ready to watch a demo if anyone cares to show me how its done

M19 60MM Mortar build
I am what we called in Nam a "fng" with this site, please make allowances. I hope to complete my permitted M19 60MM mortar fabrication and have only a few parts and little to almost no data or prints. Does anyone have access to or own a M19 mortar? Any Ideas upon securing manufacturing/mechanical drawings with dimensions? Any sources of parts? I need the firing mechanisim housing, adapter, fiting pin bushing, fiting pin and firing lever. I have a few parts and have manufactured several other parts. I have build an 81mm "look alike" for an instructor but now must complete my own M19 before my health declines any further.
