Hi Doug and Tim!
Here I have a comparison photo:
the missile should be 9.7mm but mine is 9,5mm

:-) :-)
I used for the missile an evergreen 3/8" Tube (9,5mm). Then I cut the kit missiles in two parts. Fortunately they fitted exactly in the tube so now you're able to adjust the lenght of the missile. For reshaping the front and the rear I used:
First I used the miliput for reshaping the front and the rear. Then I left it to dry for one night. The you must file, sand it down to the right shape. Once that was done I put wall filler on the front and the rear. Let it dry for 4 hours and repeat the sanding. So it is pretty smooth now. I'm curious how it will look like when painted but that's how we say in Holland, "Zorgen voor Morgen" :-)
Thanks for your interest
