In keeping with the concept of setting up drawings for scratch building I am including this. I found a drawing on the net that I liked.
This intreged me but alas there is little information on this trailer.
The Airfloat Coach Company began operation in 1930 from a manufacturing location in Pasadena, California, and moved in 1935 to a plant in downtown Los Angeles. Company owner Omar Suttles helped organize manufacturers into the Trailer Coach Manufacturer's Association, a trailer trade organization. Airfloat patented the roof ventilation system, third-wheel and a double exit door. Models include the Commodore, Presidential Landyacht and the Skipper. Airfloat shuttered the doors on the factory in 1957.
I did find a 1947 for sale that had all 4 views, so I made up a basic drawing and some front and rear half sketches. The 1947 was fairly close although it had been cobbled together and the door replaced It did give me some basic clues I did not get from the origional photo.
From there I was able to come up with a relativly in scale representation that is quit credible.
You can develope yourdrawings from any reference that you ave with a little care and scale reference.
You measure how wide a car is and how long it is and you can guess from there other dimensions, if you have nothing to go on. I had no dimensions for his but used common ones from other trailers.
