I know we are only dealing with one example, 1013657, but in my mind we are now looking at the possibility the 1.01 numbers were held as spare recievers post war. The late 1920's it the time when the W&S rifes were all reworked back to standard configuration. It would not make sense for an already converted 1.01 to be sent in to be reworked along with the scoped W&S rifles, unless it was a spare reciever that was finally converted. The above mentioned 1.013 example could have just worn the bore out, poor scientific theory to use one example as the rule, but that rifle causes more speculation in my mind. I understand we are dealing with no absolutes and scarcity of information on the subject but this rifle points me into a circle. I fully accept and understand the surplus of W&S rifles post war and don't see the point of keeping these late recievers as spare parts but this one example has me puzzled. I guess I'll need to wait on a dozen more to surface to understand a little more.
