Many thanks Hugh and Michael, also hope what you see helps Michael.
Cold and damp again today so no spraying yet again, but we have made progress.
This is the beast as it looks at the moment, squat, ugly and a god-awful mess, but were getting there.
Decided to make a start on the beaching dolly and thought the tyres would look better if they were flattened and bulged a little. I've never attempted this before so after flattening the wheels, I stuck them to a bit of plastic and applied filler on each side. This set overnight and then the wheels were removed by saw from the plastic and filed back to shape. Here is the outcome.
While fiddling with the wheels I also set about the dolly platform. To my mind it would have been a very strong and heavy local wood, such as oak or beech which would have been liberally treated with something like creosote which would have given it a darker appearance.
These are most of the bits painted and drying.
Last of all, the propeller which on this version of the Arado will not have the spinner fitted.
