Well, apparently I missed it. Of course, I'm an infrequent visitor to Gunputz these days - and how many bazillion posts are there in that thread now? Not a surprise that I haven't kept up with everything in that thread when I'm not a regular on Gunputz. It is a thread that I often refer people to who have questions about Husqvarnas because of all the info - but I can't keep up with it.
It's only been eleven years and 2,400 posts since you started that great thread, right? That's a lot to keep up to date with! (BTW, at least for me, the thread link you provided in your post ends up as a "404 Not Found" result.)
Well, that's interesting to know. I never bothered thinking to compare before on my other three Husky's. But this rifle will be listed on an ATF Form 6NIA, so when I started looking I noticed two different serial numbers in two separate places. So Bill Leeper will be putting the serial number on the action on the new barrel. It's unlikely US customs will demand the barreled action be removed from the stock because it's an obviously non-factory barrel with the serial number on it. But they have done some odd checks on firearms I've taken back and forth over the border the last 25+ years, so nothing is impossible. I don't see any good coming out of having one number on the action and a different number on the barrel when they're checking serial numbers against the import documents.
So... the official serial number for these Husqvarna sporting rifles circa 1960's is the serial number on the barrel, not the one on the receiver? Either way, to keep everything in agreement I'll have Bill repeat the serial number on the bottom of the receiver on to the new barrel, and use that number as the serial number listed on the ATF Form 6NIA.
My packrat tendencies lead me to think I should keep the original Mannlicher stock, barrel, trigger guard floorplate and action, for my estate to sell with the rebarreled/restocked action as a complete package to give potential buyers options when I'm gone for the long dirt nap. Not impossible that by then an original Mannlicher style Husky could be a lot more valuable than that action with a custom barrel, stock, and steel floorplate.used to build a custom barrel.
But then again... there's probably some other Husky fan out there with just an action, wishing they could find the rest of the parts to bring it back to being a hunting rifle again. If I had a Husky action only, that's exactly what I'd be looking for.
