Hard telling but in your first group the third one down from the top on the left side I've seen on 99s dating back to the 20s and maybe earlier. They seem to fetch good money. The bottom sight on the right seems to have been used on the 340 series of rifles. The Marbles in your second group I think were all pretty much generic replacements that were made more to match a front blade height than a given rifle. I would be interested in the little folder on bottom of the right side in the second group if you decide to sell. Best of luck with your investigation.

What's the chance this two-hole sight on the bottom left will fit my 1919NRA
Great, if you only use one hole! I wasn't sure but it looks like a sight for the later Remington model 121's & the 572's & possibly a few others.

They were made in three heights and with the small sliding adjustment one of the three would work with almost any gun so there isn't a specific code stamped on most of them - the only versions that might have a code would be the ones with special bases - they were also made with a narrower dovetail for early Stevens rifles so measure the dovetail) and with screw on bases for guns like the Remington Model's 8 & 81. The XT, extra tall, I believe is only cataloged for use on the Savage Model 1920 and I don't believe they have a code on them.

I didnt see any letter code on it, it is missing the insert but the screw is there. Were they spring loaded or did the elevator keep it in place? it measures. .381 at the widest point.
Top 2 on left are Remington 701's, common sight used on several models and often found as a replacement on other makes (there's a 1899 for sale now with one of these), next to them to the left is a Remington or possibly Meriden used on 22 cal. The one with two hole is possibly Remington for 22's. Far right top is a Winchester, broken & missing parts.
Bottom left is a Savage No 20, version introduce in the mid-30's. To the right of it are various Marble's aftermarket sights.
