Yes, the photo with the tall leaf is a Lyman #6. It was superceded by the Lyman #16 in 1955.

The link Calhoun provided should enable you to identify the tang sight. Lyman 1A and 2A are not windage adjustable. Lyman 29 1/2 and 30 1/2 are windage adjustable. All of these tang sights were discontinued by 1955.

And yes, these sights were all after market.
