i found this old thing for sale locally, and the seller doesnt know a thing about it. he thinks its a 1961 dynahoe. from some quick googling, it does appear to be an early model dynahoe, but i would like to confirm what it is, and find out what the specs are.
Think it's a model A Dynahoe, weight is around 12,800 pounds, it has a F244 continental engine, Manufacture was the HY-DYNAMIC CO. It looks like the rear fenders are missing. I had worked some in the 70's had three with the gas engine and two newer one's with detroit diesels.
