Cheers Jim.
Yep, I'm particularly concious of the spike on the nose, I just know I'm going to break it off.
Had a frustrating afternoon trying to find this bit.
It's marked a E194, but that part is actually a completely different bit that goes on the top. I spent an hour looking over the sprues and instructions and couldn't find it. The closest bit was this.
This is the right shape at the back, but completely open at the front. It looks like it wants another bit glued to it, but there's nothing on the sprues which corresponds. I'm therefore in the process of gluing a bit of runner to it which I will shape as best I can.
