Bill,

Sorry I had you mixed up for buying them.  Yes they did go to MN but I forget the name of the buyer.

The Perkins L4 engine was perfectly OK as far as I am aware but it didn't have the beautiful tone of the P6 in the 744s. 

Both are coming to be quite sort after tractors over here and anything complete, original and running will be £5000-£10000 depending on actual condition.  Occasionally more.  Anything less than £5000 will be suspect condition wise and in originality.  Examples with hydraulic lifts are very hard to come by - they were totally different set ups to those found on the 44s in N America.
