Yankee 131A screwdrivers

[mikey78]

Hello guys,
I'm posting a question for a friend of mine collecting screwdrivers 8)
Does anyone know when did Stanley (sheffield) stopped making Yankee 131A screwdrivers with a brass finish ?
This is not my field of interest so if anyone could help it would be more than appreciated

Thats a question I'd be interested in knowing the answer to as well!

I can narrow it down to after 1946 (see this post: stanley-yankee-age-estimation-t100558.html) as thats when Stanley bought out North Brothers "Yankee" who made the familar "Yankee" Spiral ratchet screwdriver. I think all my North Brothers ones are brass.
