What does the staking on this 2.197335 STD. PRO. dovetail tell us?
Is there evidence of once having a type 1 rear sight? (See red circle) Is there evidence of having been staked twice for an adjustable sight? Thanks in advance! |

The 2.23 SP I used to have presented a similar situation, of which I never really confirmed. I know the H in shield sight looked like it had been on for decades. Another note, mine was also staked on the left hand side and through the finish too.
The above picture has some striking similarities to mine. |

Did SP always stake their flip sights? I know I have an early spring tube Winchester w/o flip sight index/stake marks.

The first question is "would we expect to see an adjustable rear sight on a Standard Products"
War Baby page 463 shows milled adjustable 'H' in shield used near the end of production. It then mentions stamped adjustable with insufficient data available CCNL shows milled adjustable sights showing up as early a 2167587 which seems too early. War Baby page 468 shows International Register "IR Co" as a supplier of adjustable rear sights to SP. So is it plausible? Perhaps. What is meant by "near the end of production"? The rear sight was adopted in April of 1944. That is the same month that Standard Products made their last delivery of carbines in the amount of 18,005 according to WB March they delivered 25,000 The highest reported serial number to the club is 2,238,554 without accounting for scrap numbers that would put an estimated delivery date of the carbine in question at Feb 1944. This is why we scrutinize the stake marks. Disregarding the mark circled let's look at the bottom stake mark. It is textbook adjustable rear sight stake mark by the book. The thin edge of the dovetail is prone to breakage due to the receiver being hardened. Staking was not to be done at the edge, rather back a bit to deform the metal into the notch. Now look at the top stake marks, what do you see? Why Carbines brings up an interesting scenario, does your rear left dovetail have a staking mark? As to a rear sight looking like it was on a carbine a very long time, If it was a field replacement in 1945 would that still qualify as "A very long time"?
