Congratulations to your new rifle, it's a special K98k.
Please show the trigger and another thing is very important, take a photo of the stock completion date code, it's hidden behind the buttplate.
My assumption is that the stock was completed in July, in the 30th calendar week of 1942. Thursday, July 23, 1942 could have been the exact day. If my assumption is correct, you could find the code "Mü 4 30 42" behind the buttplate.
Will finally came back. Currently on display in spot usually taken up by my M1D sniper that's out getting some tlc... need to figure out how to rework racks to accommodate them all before D gets back... is nice seeing variety again though lol.
