Thanks, Tx Jim!  They have no serial numbers listed, but most of the specs fit, such as engine size and fuel tank, capacity, etc.  Any info that I can get on her is a huge plus to me, and I appreciate it all!  
She was pulling a brush hog, not very long ago.  However, she no longer has the battery crank attached, (it RARELY worked when it was there), so is hand crank only.  I have a hard time getting enough "OOOMPH" in my arms and shoulders to crank her, with the hand crank, against her compression.  Some days, I am better than others!  If I get her restored, I'll put the battery crank back on, and hope to use her more often for stuff, since it won't be so hard on me.
