A modest portfolio.
There are some machines and power tools that I’ve done hundreds of, and there are others that no one else alive has ever had on the bench. Frome the lowest-budget homeowner tool of yesteryear to tools built specifically for government contracts, all of these machines have value, historical, sentimental, or otherwise.
Here are just a few examples.

The O-3 was a short-lived design of the 1920's, being replaced by the more robust O-4 by 1930.

This 107 1/4" drill field coil needs a bath.

Freshly cast B-9 belt sander tables and brackets, ready for machining.

My 1966 Rockwell vertical milling machine before I fixed, well, everything.

Radial arm saws aren't inherently dangerous, despite the old wive's tales bandied about. However, having a flat belt clicking away a few inches from your pizza-eating hand is a wee bit disconcerting. The Beaver combination woodworker never fails to capture the operator's attention, one way or the other.
