I bought a M1 from P&S last year,..its a Harrington&Richardson M1,..overall im pretty happy with it..no rust or corrosion,..and a nice bore too.
I think your look nicer than mine..your stock looks mint...and your operating rod looks like new as well.
I think these M1's that Jean has, could be from Jordan,..as he mentioned that they were from a dry climate,..that explains no rust or corrosion
