Probably so.  The barrel on mine is like new, maybe even unfired.  I believe most of the 1897 Steyr-made Krags went to Norway's Civilian Marksmanship organization.  They probably had more of the 4500 in storage than in use.  Then the Nazis came along.  There is much info about the Stomperuds online, you'll run into more than a few of my posts.  I actually got lucky with my stock set.  It came from Steyr too, going by the serial # on the buttplate.  Because of the size of the upper barrel band that came with it, it isn't going to be a simple cut in one place operation.  I've seen some variation in Stomperud  forearm images online.  I'm going to have to make two cuts, and the band will be forward of a step in the barrel, where it'll fit correctly.  That's going to require some splicing and blending in of the foretip.  They must've had some larger bands in order to make it fit behind the step.  Some of the Stomperuds in circulation might very well have been assembled by home gunsmiths from the $10 actions.  I know in one case that some home gunsmith's answer to my band fit problem was to turn the barrel down to the correct diameter.  I'm no going that route. 

I would like to get it together and use it at Camp Perry in the Vintage Rifle match one day.  One thing I noted on mine, it appears the root of the bolt handle bears a wee bit more than the locking lugs.  A little stoning on the back edge of the handle will fix that.

I've had a few people warn me that the Norwegians didn't like doing the work, and would sometimes sabotage the items.  About the worst that could be done would be to overheat the receiver, it's plenty hard, so I don't worry about the rumor.  It will get fed reasonable loads though.
