We have another piece today from our interview with Dolf Goldsmith, this time on the subject of $5 Finnish mortars used for fun and profit. Well, actually just for fun. To clarify one of Dolf’s comments, I believe these mortars were Soviet made, and Finnish captured – the Finns used mortars made by both the Soviets and Western powers.
Sure would like to get my hands on a Finnish-marked mortar!
as is often the case, Jaeger Platoon likely has the best information concerning this sort of Finnish war time hardware: http://www.jaegerplatoon.net/MORTARS0.htm
He described “Ampulomet”. It really used 12g shotgun blanks for firing glass or metal round filled with incendiary liquid:

Both you and Dolf are technically correct — under the circumstances described, 82mm was definitely a standard Soviet mortar caliber, versus the more common 81mm of almost every other country.
