I just picked up an ariska , only number to be found is a 21 stamped here and there , no other marking whatsoever . We narrowed it down to a type 38 but it wont fire . when i remove the bolt the take the bolt apart it only has one long spring on the rear of the firing pin , nothing up front . it all seems to be there but it just wont fire it. its like the trigger wont move or its bound up . it moves nice once the bolt is out . Im not a huge fan of this gun but it was lonley so i took it in . what round does this take , would you even shoot it , is any one familiar with the workings of one ?
