Wanted: Wafer for old American-made wafer switch

[KN4SMF]

Specifically, wafer #2 of the wafer switch assembly on my BC 348 is burned up. This assembly has 2 separate and identical wafers. I don't necessarily seek that particular exact BC 348 part and there were certainly a number of other American made things from that era that may have a wafer like what I'm hunting. It has 4 identical contacts on the round inside, and the contacts are long-short-short, long-short, short, etc, for a total of 4. I have attached photos. Thank you.
