The coolant overflow recovery tank described above sold for US$225.50
I wonder if this one will go as high?
https://www.ebay.ca/itm/1937-thru-54...K/293150321386 I suspect it may be a repro as the listing says it is the last one, with 10 already sold. The listing also references "Counterpart Automotive" part # 41-8255.

Counterpart is the wholesale side of Car & Truck shop out of orange, CA. They are importers of many truck parts and wholesale to a lot of retailers."
Sure enough, the tank can be found at
