What was the last year for the Snowmobile Attachments for Ford? I have seen them on 1937 Fords, and one on a 1940 Ford. I found a parts brochure that lists all parts for The Arps Corporation Snow Bird and it lists parts all the way up to the V-8 Fords. (1932 and up).
Mr White started his Automobile Snow Attachments around 1913 and changed the name to the Snowmobile Co about 1920. The F-S Mfg.Co., later known as the Arps Corp, purchased both the Snowmobile Co and the Snow Flyer Co. in 1932. all three units and replacements parts were produced until 1941 the start of WW II when raw materials went to the war effort only. After the war production was never restarted. All the units were made mostly for Fords but some special orders were also made.
