Small Engines (Lawn Mowers, etc.): ANTIQUE RIDER, suicide knob, steering wheels

Question
I was just given an OLD rider, three wheel,drives off the front wheel by chain, and belt engagement by hand near the steering wheel!  Have ANY IDEA what make or model this could be...................also have two of the ROOF 3 wheel mowers but steer like a bike, this rider actually has a steering wheel with a WOODEN suicide know!
Obviously there are no numbers on the unit anywhere
Hope you have some idea.............been checking web-sites.
Thanks

Answer
Hello Pete:

Give me a Few days, Please. I have Spoken with a Few Older Mechanics and have been Told that Roof Manufactured a 3 Wheeler like you Described. I Understand that Roof Made Mostly Handle Bar Steering and a Few with Steering Wheels. The Suicide Knob was Most likely Added by a Previous Owner. It was Not Standard Equipment. Hope this Helps. I am Here if You Require More Assistance. Let Me Know What Happens, Please. Thanks.

Good Luck
