Type30collector

No I haven't mounted it. I'm about four states away from the bayonet at the moment. I thought it was a trainer initially, but the S319 is making me wonder. I found a reference somewhere to arsenal 60 in China, but there's no markings. My best lead on the "S" so far is this site: http://www.conknet.com/~mrj/other.htm where the Finnish Civil Guard Type 30 rifles are said to have been stamped with an S and a four digit number

I have an unmarked type 30, variation A, standard size, hooked guard, wood grips, screws with oval nuts, contoured handle, deep fullered blade. The scabbard is a standard issue metal. This bayonet has no arsenal marks at all, and the only markings are S319 on the end of the pommel. So far, I'm told that it's a production blade, not a trainer, possibly a prototype and that it might have been a blade sent to Siam. I wouldn't have expected to see "S" in the serial numbers coming out of Japan prior to WWII. Does anyone have more information? Thanks!
