Hi
During the late 50's and early 60's I drove an M62 doing recovery work in Cdn Army. Started in Diamond Ts and Macks then Halalouya THE M62 arrived. It was like someone finally thought of us poor reccy mechs. Glad to see someone is keeping them alive and well. As to the cover on the boom operaters seat, the originals had no cover. We created our own as we used them in all weather including at 30 below and snow so it at least kept us a little protected. Our workshop canvas worker made the covers to suit the bows and we all had slightly different setups, I had curtains on mine that rolled up and tied off for summer work or if it was frosty and couldn't see with them down. Have fun and don't break a cable.
