Donning my chaplain's persona for a moment here.....
We are taught to be good stewards of everything that God has put on this earth. I believe that that extends even to the machines that man has designed and built, by the grace of God and our God-given industrious abilities. With that setting the stage, I can readily see God looking down upon you, PapaBear, and proclaiming, "Well done, good and faithful servant. I have trusted you with a fine piece of history worthy of preservation, and you have answered the call to polish it once more to it's former glory."
Shall we all thank God for how we are used to enhance mankind, His kingdom on this earth, and yes, even through these old MV's.
Praise be to God!
