Merry Christmas & Lancaster Teaser

Thanks Monguse.

Sounds like I need more info. I thought the cutout switches above the starter switches were for MK III only, since the Packard-built had different carburetor that had to be forced off on engine shutdown. If that is so, Old Fred should have those switches. Maybe it ended life with RR engines, and the switches were removed to avoid pilot error. There are other peculiarities, but I believe this is the big one.

EDIT: I've since seen some sources that say Old Fred was built as a Mk I, which makes more sense. What source says it is a III? Sorting this might uncover other useful info.
