You have a rare rifle. I have one as well. I did an analysis the number of 1941 LB's made, the number of /2's and /3's made, and did a percentage adjustment of how many of each model and make could be expected to have been converted. It's all loosey goosey, but it's all I've got. Based on the numbers made, I speculate that less than 1,000-1,200 Long Branch /2's made. It's been a few years since I did that, so my memory may be off. I'll try to find that work I did.

So to your rifle. Since it was a rebarrel, you can find a donor rifle of the correct make and year, (hopefully a non metal cut sporter) to make yours right. The /2 wood will be some easier to find. It's out there, you have to hunt every gun show.

I'd spend the time and money to get it restored. It's a rare piece.
