I'm still here. Back in the late 1960's Pop had a shop and two wreckers. A 1960 Ford F500 and a 1959 Ford F250 and I towed with both . Out of high school I started working for the electric co. on their fleet as a mechanics helper. They were using this 1959 Mack with a Holmes 750.
Moving up they remounted the 750 on a 1971 Autocar. That is the truck I towed a lot with. (still looking for a picture of it) Years later I was working in the machine shop rebuilding hydraulic components and running the lathes and milling machines.
More recently I found for sale a Holmes 330, very similar to the Holmes 220 that was on Pop's 1959 F250. So I started the quest for the correct truck to receive this bed accessory.
So here it is, the day I brought it home on the back of my hobby wrecker:
This 1956 Chevy 3800 is the perfect truck for the 1955 Holmes 330. Work in progress, will provide this old man a classic ride to the local car shows.
