Thank you so much everyone; I'm blown away with all the offers of help!!! I'm not going to be able to get the amp to Dave in time for his departure tomorrow as it is stored in my sister in laws garage and I won't have access today from work. BUT this has really motivated me to get something done about it, so I might need your help in future!
I was looking for a pic of the amp, but all of the photos are so old they won't be digitized! I did find a grainy shot of the Marshall from 1990 or so, and another from a party in 2012 there I'm setting up and you can see my Ampeg head and the 4x10 cab:
