...cost an average of around $1400 new, are now averaging over 50 years old and, in good condition sell for $2000-3500 today


If only all our equipment held its value like that... Actually, that's not a half bad way of figuring out a portion of this "per hour" cost. Take the difference between the current selling price of some used machines versus their original cost and divide it by the number of hours they've been used.

The challenge is going to be deciding which lines have been around long enough to look at (L3000 and B21?), and figuring out a good estimate for their original selling price. I suspect that there are plenty of people who frequent this forum that purchased tractors in the 1990-1997 time frame... with their help it'd be possible.
