farmall H

Went to look at a H today. Good chance we will be bringing it home just a couple quick questions. The serial # is 117824X3 whats the X3 for and what year is this? 1945? he wants $600 firm and it hasnt been run in 1&1/2 years. So it is believed to be stuck but has been kept inside for the past three years. Needs two new front tires but back have a ton of tred. not too bad looking and pics to come. What you think on the price?
thanks taylor
