You will probably like it if you like finely made rifles.
M38 is the handiest and latest made, what with the shorter barrel and turned down bolt.
I like the long barreled M96 made before 1914 because of the nice walnut stocks. The Swedes switched to beech after WWI started, due to shortages, and stuck with it after that date. But it is harder to find one of these with a good barrel, in my experience.
The straight Swedish stock comes up to my eye like it was made just for me, but the grip is more akward than the later Mauser pistol grip.
Sights on the M96 are usually of the old 300m closest setting and shoot too high at 100 yards. Later M38 should have sights that go to 100m.
I don't have an M38 yet. I have an M96/M38, an older M96 that was cut down, the bolt left straight and the old 300m sightts retained. It doesn't actually have the advantage of either model.
Beware, if you get into these Swedes, you eventually want to get all the variations. They are addictive. So it might not make much difference what you first one is.
As for the add, they have been saying this for a couple of years now. No doubt they will eventually run out, but who knows for sure when that will be?
