Hammerdown

Howdy All, Still trying to figure out how to work all this.

Am trying to find the origin and other information on a very early 1900's horizontal single cylinder engine with external timing gears with 5'' bore and 6'' stroke, is also water cooled. Most casting numbers are a variation of 200. It looks to be American made.

Any help would be appreciated as I want to build the correct vehicle around it again.

Also have pictures in my vehicle gallery
