Was the first Power Horse built about 1934? Even Mr. Bonham can't say exactly when it was first assembled. Shown above is an 'after' picture of the prototype. See next page for the 'before,' and a picture of Mr. Bonham.

I own the Power Horse, but Mr. Clark Nelson, of Nelson Inter-Mountain Crane Service, is solely responsible for doing the restoration.

The ski trails seen in the background of the picture will be the site of part of 2002 Winter Olympics.

Ed.'s note: Below and on the next page we have reprinted the text from Mr. Bonham's patent application for the Power Horse.
