I picked up on an older subject/write-up where others that have stated that a barrel obtaining the “Oval P” might have been fitted by Winchester:
The nickel steel barrels are equally analyzed, getting subjected to your pressure 30 % in surplus of tension created with the cartridge the barrel is meant to be chambered for. Soon after evidence firing a barrel is carefully inspected and when it reveals the slightest sign of strain, or imperfection, it's condemned. A barrel that passes the proof is following straightened, after which you can offered the second or “finish” uninteresting. It truly is then straightened yet again, and then it can be subjected to what is named the “Winchester” or “Guide” exam, which never fails to reveal any irregularity in the inside of the barrel. This take a look at is recurring following the barrel is rifled, for the purpose of detecting any achievable disturbance in the bore in the course of the latter process.
Thanks Bert for the additional information and facts. I wasnt informed that each the barrel and receiver were being struck Together with the “WP” in the inception of utilizing the “WP” evidence, nor that the “Oval P” didnt show up till 1908.

fifty Each individual–almost 4 months buy a Civil War solider. Regardless of the noticeable superiority of your repeating rifle over muzzle loaders of the working day, it absolutely was very well following the Civil War prior to the US Federal government acknowledged the repeaters, modifying warfare eternally and producing the muzzle loader obsolete for future wars.
Ned Schwing said in his reference book to the Model 1890 & 1906 that Winchester commenced evidence marking them in 1908… I do not know if that is definitely correct, but will think that it is. The “WP” evidence mark was used following the barrel and receiver were being mated, assembled and finished. This is very evident about the firearms manufactured while in the late teenagers by means of early 30s in the event the blue flaked (popped) off when the proof was struck over the receiver frame.
