Solved: Model 52 Hammer Types?

[-db-]

Recently acquired a large lot of Model 52 parts and have a number of two types of hammers. Photo below shows the differences. Can anyone tell me what these are? Thanks in advance.

Hammer on left is single action only.

Hammer on right is traditional double action/single action.

Both hammers have a half-cock notch.
