Hello all, The Inland in question appears completely original and unmolested in every aspect. There are none of the tell-tale signs usually associated with "monkeying around". 12-42 barrel date, checkered safety, long face mag release, I cut high wood, type one barrel band with no print in the wood from a type two, everything is perfect, except... it has an RN marked flip sight. Zero indication of being changed, no punches or stake marks. I know Inland received sights from other contractors, but I can't find any record from this serial number range. Has anyone else got a NPM sight on this range Inland? Thanks for your opinions and help!
