Wooden sided box trailer

The trailer was probably from the 40's 50's it was about 20 plus ft long and 8 plus ft wide. The sides were wooden made of 4x12's 4 high if I remember correctly and of steel bottom. Might anyone know of its origin?

Wheres the picture? completely random but I am moving up to Fort St John this friday the 25th.

Sorry no pictures the different boxs were a 2 rock trucks regular box and something else that was very heavily built, were from the 40's and 50's. It was funny after the fact. Dad told me to cut the 1/2" chain that went across the center of the box and who should appear but the owner of the property and land that parants had bought from.It was back and in the trees so was hard to see from the road and even if someone was driving by ..... Never did figure that out as a 15 yr old. I was using the JD-420 in the back of the property (Duncan) and I heard a "WACK" There was George laughing, with his machette in his hand asking me what I was doing. AAAAHHHHHHH He laughted. Lets go for coffee sometime if you like.
