Buying 2nd hand kits can be a bit of a gamble. Hopefully everything is there.
As it turned out, the poly caps was missing, and I forgot to check before starting the build. I simply didn’t think of it.

This is how far I’ve got before shutting down the build for now.

If I can find 14 poly caps (short ones according to the instructions), I might get this build started again and perhaps even finished.
