So this is one rifle that makes you wonder where to post it. Is it a Mauser? Is it Japanese as it was made at the Koishikawa Arsenal?
A RS121 Type 46 Siamese Mauser or Arsiaka, made in 1903.
Picked it up a few weeks ago at our local gunshow. Still chambered in 8x50R so it missed the 8x52R upgrade of the 1930s. Overall in great shape so I'm happy with it. Picked up a bayonet for it, which arrived this past Friday, have a reproduction cleaning rod on the way. Just need to settle on an appropriate sling and muzzle cover for it.
Already looking for my next boom stick to add to the herd.
I originally translated the serial number as 39316. Now I'm also seeing it as either 35316 or 34316, I just can't decide on the second digit.

Not saying these things are rare, but supposedly only 40,000 were made. But it's the first one I've seen in the wild since I started collecting in 2011. That being the case I just had to adopt it.
Now that I have one, I'll run into them everywhere I look now!
Nice score! These are definitely difficult to find in the original 8x50R. I have one in 8x52.
I cast a vote for 39316. The rear sight ladder seems to be in a somewhat different font, but it's still helpful for: 0, 1, 2, 4, 6 and 8. Some of the serial number numerals are struck poorly and/or worn.

Now I'm thinking of looking for one of the converted ones to add to the herd. But finding the bayonets for these things is a pain in the backside that is for sure.
I have one too in original 8X50R chambering I picked up in an estate package, $450 for the lot. It was the last of the dead guys stash that his family raped him over for and the last Kali Cash & Carry buy before they did away with it in 2014. I scored pretty hard by my meager standards. One of the sweet deals was some complete furniture for a 1917. Took me 3 or 4 years to find the right Eddystone sport job donor. PAX

That was one sweet haul you got there.

Yes it was, I was beyond ecstatic when given the price. The Carcano 91/30 long rifle and a T99 got my initial fundage back. The little Savage 325 in .30-30 had a jammed bolt and minor mechanical mess ups and the stock was toast. I did the best I could with the wood, added a recoil pad and decent sling then let be. With pointy boolits it's very accurate. PAX
