A newest member’s acquisition

[jeffhuey1n]

Howdy! This is the first of many posts I hope to make. I’ve got multiple Remington firearms with slim to no information on them. Today, I’d like to put forward my newest rifle, a Modelo Argentino 1879 EN. The serial number is 13xxx. The serial number is stamped on the L/H side of the bottom tang. There’s a letter B on the barrel base, left hand side. On the bottom of the barrel is the number 64. Very faintly there is some writing on the left hand side of the butt stock. The wood is so-so, mostly okay. The barrel and action have residual spots of bluing however it appears someone used a file of some sort to clean it up sometime in the past. There are good strong rifling in the barrel. I’m going to try and post a picture. Unfortunately I’m not much of a cameraman.
The only question I’ve got for this post concerns the “caliber”. What is a 64 caliber?

Unless your Argentine rifle has had the chamber messed with, it is chambered for the 11 mm Spanish (.43 Spanish) cartridge. The numbers on the sides of the tangs are not serial numbers; Remington did not serialize most large frame Rolling Blocks. As for the "64", only the Argentines would know the significance. I checked my file cards for both my M 1879s and neither has a number on the bottom of the barrel. The letter "B" is an inspector mark. Markings in the wood indicate issue and use by a genuine Spanish-speaking country.

Thank you for the reply. Here’s pictures of my rifle.
