Graeme, here are a couple of in progress pics I took when making the springs for the other side
As well as winding and adding the springs to the other side I have been adding all kinds of small and tricky little bits and pieces

these tiny etch brackets each got a microscopic plastic bump stop (I think) added to the top, after numerous attempts punctuated by periods of scouring the floor for them

here they are installed on the sides of the suspension turrets - no location points provided and just a vague sketch in the instructions so had to guesstimate a position and then make them all match

jack added to front right wing
angled lifting eyes added to each wing
tiny hinges added to the hull side windows
rail added to rear deck for the open roof to sit on

exhaust pipe added
mudflats added to front wings
hinges added for side door and then side door hung in place

etch locks added to side bins
end of exhaust drilled out

headlights in place - unfortunately the right side had drooped unseen

tried to correct it but of course it sheared off so this will now need drilling and pinning

rear lights add to rear wings

side window hinges on other side

another shot of the roof rest

there are still lots of small fiddly bits to fit - the GB finishes next Sunday - this will not be finished on time
