That is the nice piece of Imperial Russian MG, reissued by Finnish army, looks like it has a big history...
I know that in Europe the new "Ukrainian" examples 1910/44 for sale at range of 700-900 eur.
Imperial Maxim must be twice higher in price up to 2500.
But I heard that one deactivated gun ( ex Finnish re-issue ) was sold in Russia to the rich guy for 55000 USD
