Alltrol gas stove burner valves, replacement parts for cooktop or range

Lot of three Alltrol control valves for stove or range top burners. These are vintage new old stock and we don't think that they've ever been used.

The valve bodies are solid brass and they measure about 2" over the valve and 3 3/8" long over all. The only identifying markings are the Alltrol name.

The control knob shanks are about 0.35" x 0.22" and about 1 1/2" long (one is slightly bent from storage)

There is also a brass blending valve marked Harper #38 Gas and Filter 1/3 C.F.
