Anyone care to recommend a spark plug or spark plug options for a 1934 eight?

I've been using the Autolite 303 in my 1934 Eight for many, many years. An excellent plug for this engine with the added plus that the nipple unthreads so you can use correct knurled thumb screw connectors if you are authenticity-minded. I've also used the Autolite 308 with good results but they won't accept the wire end eyelet and knurled thumb wheel connectors.

Sadly, I'm told these plugs no longer come with proper black oxide shells, so you can either put up with the cadmium plate appearance, or chemically blacken or paint them.

The wire looks white in this photo but it is the correct gray.

When I bought the car, the previous owner had AC 45 spark plugs. Any thoughts on acceptability of those or comparison to Autolite 303?

AC 45 should perform just fine.
