I did the sender on my 34 perhaps 15 years ago and redid it as original with cork, coated with shellac. I bought the raw cork cylinder from one of the industrial supply houses, perhaps MSC or McMaster or similar, it wasn't hard to find. Despite the 10% ethanol in current gasoline it has continued to function just fine, but given that ethanol is a terrific shellac solvent, if I had it to do again I'd fit a brass float, there is a good possibility that the ethanol content may increase in the near future, so why not avoid the possibility of having to switch over then?

Atwater-Kent remanufactures quite a variety of vintage senders with cork floats, you might contact them if you're really committed to using cork.
