Larry,
  Here is my guess:

1000 tractors cost                                    78230.85
970 tractors sold @ $125                         121250.00
profit (raw)                                             43019.15

Cost of #3 restoration                             29171.49
  profit (raw)                                          13847.66


Raw profit per 970 sold                          14.27 per tractor

It looks like we should have made the $14.27 per tractor sold.  However, our organization paid shipping, handling, insurance (and possibly advertising in HPOCA and other publications) plus we also don't know if our raw costs of the tractors were F.O.B. to the HPOCA.  That might be where the difference in expenses is.  
  That's why we need better minutes and accountability which I believe will be forthcoming with the new leadership.
