What model erickson?

[Malfy9295]

New member, first time post. Just recently purchased a project skidsteer. I cant find any information on which model erickson skidsteer i have, there are two name plates, one says specially built and designed by erickson corporation and the other plate says model k-15 with a serial number after. It appears to have a wisconsin v4 gas engine, i understand erickson built fords cl20/30/40 models, to me it kind of looks like the size or a cl30/40 but the frame is not strait and level to the front of the machine like those models, frome the rear of the machine the frame slants downward to the front so that the top of the front tires are above the frame/chaincase. Any information on any erickson skidsteers would be helpful, i will try to figure out how to post some pictures
