Who'S the resident Lauson engine expert?

Trying to figure out the HP and approximate age of a Lauson engine. I'm hoping it's at least 2.5 hp. Been searching the web but not much info on the motor. Seems like it might have been a reel mower engine but that's about all I can figure,not sure though. Any help isappreciated. Thanks

Thank you for the links, alot of info. Hopefully I can figure out the hp. Just from the little bit I read so far it appears to be a 1955 motor.
