WK-40
'FBB' engine 3-3/4x4-1/2
engines WTM 501K to WTM1911K, WKE1912 and up

1935 WAC or WDC 501 to 1440
1936 WKC or WDC 1441 to 5119
1937 WKC or WDC 5120 to 7664
1938 WKC or WDC 7665 and up

in early '37 the 'WA-40' was discontinued and changed to 'W-40' since the engine would burn both fuels

'W-40's fitted with the kerosene engine would be called 'WK-40's in August '36
