I'm suprised about the estimates...
Surely the 175 would be worth more? It looks nice original condition! Not sure about the aluminium on the rear of the right wing though!
Dome looks OK for an orignal, and paint looks quite good for the year! (if original).
Wouldn't it be worth nearer 10k?
Also I thought the P50 prototype would be worth more... I guess the normal one would be worth more than the prototype, because its the "popular" one, but only 2 prototypes are surviving!
Time to get a summer job to attend the auction
