Kar98b "S28" version with SS-TV marking

[konopka]

Hi everybody,
What do you think of this - IMO very rare - Mauser Kar98b (very early "S28" version with blank receiver and S28 marking on several parts, same serial number on every parts, blank bolt but with light matching (hand)numbering?) with "SS-TV" marking under the barrel? I think it has been somehow "rechambered" in a 8x54 S caliber, turning the barrel so that the SS-TV marking, once just visible above the wood, is now on the lower part of it - and so invisible. The french deactivation (AN + crown marking)  made the "V" disappear 
Do you think this SS marking could be genuine (I never saw such one on a gun)?
Thanks in advance for your comments and thoughts 






































This particular specimen appears in "Karabiner 98k Volume 1: A collectors guide to the development and production of the German K98k service rifle up to 1938" by Michael Steves and Bruce Karem (N°182a with "h" and 3 "O" with crown), but without any mention of the SS marking:

Great photos, with an interesting rifle.  I wish I had the answers for your questions.  I would love to have that rifle.  It looks like a real keeper to me.   Thanks for posting photos of it.

Yes it's a very interesting rifle and thread. It's a shame that it was deactivated. I thank God and our country's founders that we have the right to bear arms. Thanks for posting.
Best regards,
John
