>>If it's the same thing, over and over again, then it's probably an apprentice practicing on something that's been discarded.<<
It's got the capital letters, etc; so I agree that it's possibly someone practicing, and that the engraving is coincident.
Still; the original purpose of such an expensive pc of mtl?
Expensive, expensive, expensive.
A very expensive custom-designed part that HAD to be brass.
And very heavy; heavier that a normal wearing surface. If you were going to have something bear or wear against any thickness of this, it would be SO heavy, the bearing object, that a different design would be used altogether.
In my experience in machining, brass is used where you want a bearing or wear point to be softer than steel, so that it takes the abuse. Absorbs the wear, wears out, and is replaced; leaving the larger, more heavily vested main part, unworn.
I saw a lot of brass surfaces and packings, but never anything like this.
I bet my old mentor would know exactly.
I bet five dollars. |
