I've seen pics of the FN49 bayonet online and it looks like a Mauser 98 bayonet. Is it interchangeable with a Mauser 98 bayonet for the same caliber rifle? For example, both the FN49 and vz. 24 come in 8x57mm and 7x57mm versions. Would bayonets for an 8mm FN49 and an 8mm vz.24 interchange? Would bayonets a 7mm FN49 and a 7mm vz. 24 interchange?
