Not sure about the base, but the upright is from an early version Lyman #1 tang sight, built before Lyman made some changes to the #1 tang sight which included changing to the more familiar coarser diamond knurled elevation sleeve (barrel). The early fine knurled version of the Lyman #1 normally used a "thick base". 

That sight is neat, and the rifle it's on looks to be in real solid shape. Congrats.

Hi Captn,
The Maynard was part of a two rifle lot, here is the description from the auction:

1) FRANK WESSON 2 TRIGGER TIP UP SINGLE SHOT RIFLE. Cal. 32 RF. S# 569. Bbl. 24" octagon. Late style w/ bbl. catch on right side. Combination front sight, fixed rear sight and original sporting tang sight w/ 3? staff. Receiver, trigger guard & buttplate are nickel finish. Mounted w/ highly figured American walnut. CONDITION: bbl. retains about 90% original blue w/ the receiver, trigger guard & buttplate showing about 85% original nickel. Wood is sound w/ 90% original varnish. Mechanics are a little stiff and may need attention. Strong bore w/ moderate pitting.  

2) MAYNARD SPORTING RIFLE. Cal. 22 RF. S# 11385. Usual configuration w/ 26" octagon to round bbl. that has been sleeved from a larger cal. to its current small caliber. Ivory bead front sight. Slot blank in rear seat w/ an early Lyman combination tang sight which is a replacement. Original walnut stock has added checkering. CONDITION: bbl. retains about 75-80% thinning custom blue and the receiver traces of case color mostly turned silver. Wood is sound and retains about 80% original varnish. Bright, shiny bore. PROVENANCE: Collection of Matthew Bailey. 

I'm very happy with both rifles.
The Wesson is not 32 rimfire.
The gun is a 5th model, probably a late one, as it has a flat sided forearm.
There is only one, floating, centerfire, firing pin and I haven't done a chamber cast yet, but I think it's in 30-30 Wesson.
The condition is original and I think exceptional.
It's better than the one Julia is so proud of:

He wants an very unrealistic $3500.

The Maynard is described well, It's an 1882, 22 LR, by the twist.
The barrel is not set-up for a forearm, (no factory tapped hole)you get them as you can find them.
The barrel retaining pin is a replacement.
Mr. Bly tells me that the sight is original.

Rebel - Thanks for posting the picture and details of your “82 Maynard and Wesson 2 trigger. Both look splendid, I hope the bores are equally nice. As John Bly points out the early Lyman tang sight staff adapted to the original Maynard sight base is in my view the gem here. Although there are seemingly infinite variations of Maynard rifle configurations, the number of cataloged tools and appendages is rather finite and I like many Maynard collector/shooters strive to obtain an example of each. This sight staff is rare and not often seen. In twenty years I have managed to find only two of the later Lymans which come with their own 7/8” hole spacing base marked with a “Y” as mentioned above. Enjoy having this special example.

The Poulins, husband and wife, are Jim Julia's brother-in-law and sister and their auction house is "just down the road" from Jim's.  So, while their stock is very often not in Jim's class, I'm surprised that the family tie doesn't enable them to do better descriptions, especially for guns as obviously fine and as collectible as these.

Aaron, to put icing on the cake NOE makes a mold and sells the cast bullets.

Thanks everyone.
I'm going to keep it and enjoy it.
I just hope my old fingers can load a 22
