Hello All,
It is not the same site with all the kit that I found last night. However, this one has some close up photographs of the Gar Wood CMP version of a breakdown truck. Accessed November 24, 2016 from,

There is a close up shot of what Allan identified as Spreader bars in the range of photographs
They have Holmes Crane site too.... but for the Diamond T Wreckers
Kind Regards
Lionel
