Picked up the Model 1892 from customs. Caliber is .375 2 1/2" flanged.
Bore is great but someone has mistreated it a bit. Put away wet or just not oiled enough. Very happy with it though. A surprise Holt's didn't mention that it was retailed by Holland & Holland and is marked on top of the barrel as "Shot and regulated by H&H with address". Have to load up some ammo in the next few days and take it to the range.
