Alternator repair, a little show and tell.
Brush ID.
Isolated Field Roundbacks and first series Squarebacks.
Pre-1970 Roundbacks, One field grounded.
On these, which many call "single field alternators", the vertical brush holder is cast into the housing.
(Service manual calls the housings "end shields")
The brush and holder numbers are from the retailer linked earlier and made by a company called St Mary's. The new ones I bought came tin coated like the one in the first photo of this post (38-301).
