The list for No. 00 NE was $60; No. 0 $82; No. 1 $102; Pigeon $160; No. 3 $134; No. 4 204$; No. 5 $268 and Monogram $478 = almost $15,000 today

And BTW is not at all uncommon for the Hunter Arms shipping records to document a No. 2 with damascus barrels at a later date fitted at the factory with Armor Steel (No. 00) barrels
