A while back, I made a real effort to figure out when my saber was made, or at least estimate its age. Things got murky quick. Here’s what I can tell you.
First, definitive information about the Argentine m1898 is hard to come by.
I’ve seen many of them advertised for sale over the years. All had the same grip; a black textured plastic-like material. It could be Bakelite I suppose, but I’ve never seen a cracked or broken grip. In person, it doesn’t look like Bakelite to me, but I’ve only handled a few antique examples of the stuff.
Further, according to SBG’s local expert Pino, WKC may still be making the 1898 today for the Argentine military, as the cavalry saber is apparently still in ceremonial use.
I can’t tell if the modern saber is the same as the historical one. If it is, my m1898 may only be a couple of years old. On the other hand, I seriously doubt new sabers are made with Bakelite.
I emailed WKC with an inquiry. It has been months with no response, so I’m guessing they won’t be writing back.
I suppose the TLDR is 1) I do not know how old my saber is, and probably never will; and 2) I don’t think the grip is Bakelite, but I could be mistaken.
Oh, and 3) I wouldn’t buy the sword in your op regardless of the price, but that’s just me.
Sorry I couldn’t be of much help.
Howdy Amigo, It's Definitely an 1898 Argentine Sub-Officer's Saber made by W.K.C. in Solingen for Export to Argentina. The Handgrip could be made of Celluloid, which predates Bakelite and Plastic. In my opinion, this model 1898 Sabre is Absolutely Perfectly Balanced and a Pleasure to Work with! Please Pardon the Capital Letters! My Keyboard Is Uncontrollable! Be Well, Ramiro Guerrero
