Here's some visual differences in sights. I pulled some off the shelf to give you guys an idea of whats what.

From left to right:
Back row:

A Savage #17, Savage #18 and then 3 Savage #19's. One of those #19's is marked SP on the bottom which was an early marking by Lyman for a Savage 1899 in 32-40, the other 2 are marked SA for Savage 1899's.

Front row:

A Lyman 2A SA, a Lyman 29 1/2 and then a Lyman 30 1/2.



A few oddballs:
Back row:

A couple Watson Sight Co from Niagara Falls Canada back in the 20's and a Parker Hale, all for Savage 1899's

Front row: A first variation Marbles and then a second variation Marbles, then a first variation King followed by a second variation King sight.



Receiver tang sights:

A Lyman 56SA, a 57SA, a 57B (used on 99 rear scope mounts) and a Redfield 70LT.
