Thanks to all for following this build - all the comments were very kind and helped keep me focused on getting it finished. It took nearly 2 weeks of trial and error to get the parabellum fitted. The main problem being that it is side heavy with the magazine and I couldn't get it to stay in place long enough for the CA to dry. I eventually solved this by fitting the bracket to the gun ring, then adding the gun when it was properly dry (and knocking it off again a few times...).
I'm happy with the result I've achieved. Although it won't stand up to close scrutiny at competition level, it's been a great learning process. It's the first time I've used decals on the wings and I tried new techniques for the rigging which didn't work as well as I'd hoped. Two of the lines came loose: one of the strut cross-bracing wires, which was removed and replaced with stainless wire, and the rear right side landing wire which will unfortunately have to stay as it is. I haven't added any rigging to the tail braces as it would appear from various pics that not all these aircraft had the tail rigged. Certainly the pic of this particular aircraft shows no signs of any turnbuckles etc which may hint at rigging wires.
Here's one pic, the rest are in the ready for inspection page.

Thanks again for all the encouragement!
