....I believe it was mfg in 1910. The barrel flats do not show the twist pattern. Did Ithaca build some of the false damascus bbls? Or has the barrel flat been polished to a degree that the twist is not evident? Sorry that I did not take a picture of the barrel flat and water table.....
You are correct, the barrels have been "
polished" to the point the pattern is no longer visible.
Ithaca did
not make any false damascus barrels to the best of my knowledge.
The 1910 dating is the key. Proof pressures in Europe had not changed since the late 1890's. An increase occurred around 1915 and again around 1924 (my dates are fuzzy, too lazy to look it up tonight). Those barrels were made in Belgium as Drew states. In 1910 you could purchase both smokeless and black powder shells from the Sears catalog.
Emil Flues was one of the truly great American gun designers. In the 1910 census he listed his occupation as "Experimental Gun Maker".
