I have a Craftsman Eager 1 lawnmower from a yard sale and it's missing some parts--I think my husband can figure out which ones...the problem is I can't read the model number--the silver plate is black and all the info is scratched off--just gone...Is there any way to figure this out? The picture is the closest thing I could find to ours, although our looks older and doesn't have that red thingy on the top...I can't find our camera...

Thanks!
