Here is another example of one those famous "SA" stamped 91/30 bayonets. As collectors in Finland would say "we have never seen these before." Range Koivisto AKA Finnbear which was good friends and a outstanding member of Gunboards, use to make these. The collectors in Finland noted him making inquiries about "SA" stamps and he finally got one. This has tainted the so called "SA" stamped items in this country. Here is a picture of a suspicious one.
