The skimmer- there are actually two of those in that old pit, the other is complete with wooden cab minus the boom, then there is the one pictured. They had a steel plate on each side of the wood for track pads. As much as I would love to restore them, they are too far gone, and quite a ways from my shop. The Akermans are in upstate New York, I used to work for that contractor and they also had an H7MB, it was a rubber tired excavator. They were digging hoes, that's for sure, had a Volvo motor in them too. Volvo bought them out a while back. That big old hoe you are referring to was a Koehring 1066 I believe, that pit has a ton of old iron, they had 2 1266, and an 866. They also had a 780CK backhoe hanging around in the ding weeds.
