Hello albertacowboy .....
Be careful ........ very careful...........
This particular genre are so loaded with fakes and repros, you need a very sharp eye to ensure you aren't getting taken. I always run any purchase of a wartime or earlier k98k through a number of members on here, as well as send lots of pics and details off to a few recognized expert collectors in the U.S. If I'm buying post war rebuilds and captures, I don't bother as they've been altered anyway during the refurbish process.
Your looking for an early piece, so here's a link to one of my "righteous" K98k's that's perfect and all correct.
1939 147 JP Sauer K98k - 1939 JP SAUER und SOHN GEWEHRFABRIK, SUHL

1939 147 JP Sauer K98k (lots more more pics ... click here)
Notice the detailed match of the components and particularly the fonts used. This was an early 1939 rifle, so there was a lot of attention spent on details and parts marking. The later years, ie: byf 1944 were less marked, but there's a great Collector Grade Publications book, called "Backbone of the Wehrmacht (The German K98k Rifle, 1934 - 1945) by Richard D Law", which shows what should be marked and with what WaA numbers on all individual components for each manufacturer and by individual year.
It was interesting with this particular rifle, as I had another member here who had bought a 1939 147 JP Sauer K98k, but it was a post war East German rebuild. I gave him the link above to my all original 147 JP Sauer and he compared the markings. He found a lot of parts had been changed, substituted or buffed during the rebuild process.
If you find something you want to buy and if you provide pics, I'm sure a lot of folks here would be happy to help you out with feedback.
Hope this helps.....
Regards,
Badger
