What is this bolt from?

[Edward M.]

Obviously it is a brake master cylinder banjo bolt (that holds the brass block to the end of the master cylinder).

However, this is the first one I have run across that had an inverted flair brake line opening in the end of the bolt.

Any ideas what this originally came from? It was attached to an 022 (large 022) master cylinder that came with my car.

Ed -

The 022 master cylinder casting had other GM car line applications in those days - perhaps one of the other Divisional applications used the bolt with the inverted flare arrangement vs. the Chevrolet banjo bolt usage.
