I found a Mod 43 on the internet about 10 years ago and couldn't pass it up because of a too-short experience with the .218 Bee when I was a lot younger. Three-digit serial number puts manufacture at 1949, IIRC, which would be the second year of manufacture. It is in very nice condition, which I suspect is a matter of refinishing both wood and metal, but maybe not.
I put a Kollmorgan scope on it, as it is period-specific. I was able to find around 200 pieces of brass on the internet, as well as a set of dies. Shoots very well, and is a lot of fun, but the trigger is ghastly so I shoot other rifles more and this doesn't get the use it deserves.
Anyway, search on eBay -- dies and brass still available. Some of my brass was used, but some was brand new. Super fun rifle. I need more shooting time, not more shooting irons!
