Makes two bonus posts.

Ebay thing (http://www.ebay.com/sch/i.html?_odkw=331868072877&_osacat=0&_from=R40&_trksid=m570.l1313&_nkw=331868072877&_sacat=0)

That sight was rebuilt. Before it was chromed. What makes me claim that?

Bonus points:

Udderly different eBat thing (http://www.ebay.com/sch/i.html?_from=R40&_trksid=m570.l1313&_nkw=331868081668&_sacat=0)

Both are claimed to be "1st type," whatever that's supposed to mean, but one is earlier than the udder. Which? Why?

No bites?

Chromed is earlier.

Non-bevel spring.

"But a sample size of one!!!" True. Odds are against it. Not impossible but not particularly probable.
