Had a look in Wendel and I'd go along with the Cushman ID - 3 or 4 horse in prod'n from 1910 'till mid 1930's. If it is an early one it wouldn't have had a mag anyway, just contacts and a buzz coil.
One almost feels the 'period' set up with 2 gal petrol can should be preserved - make super set dressing for a ramshackle farm ?
