Thank you, everyone for your interest in this build and kind comments. I have long thought the Pup kit as boring, usually prefering more complex kits of two-seaters. And that is why I only recently decided to add this one to my collection.
Thank you, Kensar for the vital info on the fuel gauge, this makes a lot of sense :-) It must have been connected to the fuel tank by a pipe at the bottom to form the system of connected vessels.
Richie, I have indeed drilled the holes for eyelets and eyelet-armed turnbuckles - I do not trust any other method to do rigging.
