There are repro tanks that become available now and then, from CWC Roadmaster bikes of the 1990's(?).
A repro Roadmaster tank might not be an exact match, but such preferences should depend on the owner.

Not too sure about the peculiarities of Western Flyer tanks, e.g., sheet-metal stamping differences, (if any; many were more plain looking).
A key feature in recognizing the CWC split tanks, besides the straight bottom and chevron front, is the flared tail piece at the rear end.
Since other manufacturers, (e.g., Huffman, Murray), made bicycles for Western Auto, some Western Flyer tanks will not fit CWC-built frames.
I'm almost certain the Luxury Liner tank shown will NOT fit this frame. The above description may hold true for post war tanks but certainly not for prewar. If it were me I would either find the correct tank or do without. Only place to shop for tires is @John who makes the best repro chain treads in a variety of colors. V/r Shawn
