There are many more types of type casting metals than just Linotype. If all you pigs are of similar composition then your alloy is closer to Monotype C which contains 7% Tin and 17% Antimony with a BHN of around 26.

Linotype actually has about 3 different alloy configurations A,B & C with only about 1.5 BHN difference between the three with the only real difference being the presentage of Tin A-5%.B-6% and C having 7%. Linotype in new mfg. pig form will only contain a Max. of 12% Antimony while Monotype versions A thru G contain on average 15 to 19% antimony.

Not sure if the old printer use a regeneration metal or not which was used to refresh old Lino as it would contain around 9% Tin and 16% Antimony as that could explain the high Tin/Antimony content.
