Thanks all!
It's a fun kit to build despite (or perhaps because of?) its shortcomings. Just a small update - I began yesterday thinking I was ready to give it a quick coat of primer to check for blemishes and then spent the whole day improving what I had!
I removed the weird little lump in front of the pilot's cockpit (supposed to be a windshield maybe?) and reshaped the cockpit opening. Somehow I'd missed that previously - it would have been a lot simpler to have done it earlier. I widened it slightly towards the rear and then brought the back edge forward by about 1mm by adding small amounts of Mr Liquid Putty and gradually building it up. The front edge was squared off a little in the same way.
The gunner's ring mounting was added using an Aeroclub part, rounded off at the edges, and added the gun mount using a tiny piece of .020" rod and.... Mr Liquid Putty! How I managed for so long without this stuff I have no idea - it is much stronger than normal putty and easier to file and drill too. I also moved the mounting point for the rear cabane strut about 1.5mm rearwards and 2mm upwards (the original and the newly drilled hole can both be seen on the 2nd pic below). All the rest of the strut mounting holes have also been drilled.



The wing struts were separated and mounting pins added, and the undercarriage main legs have been made from .016" brass rod and .020x.030" strip. A little liquid putty along the joining edges, and a gentle filing and the seams won't show!

I've also included a pic of Doug's decals - I know this doesn't do them justice but it gives an idea of what I got. As I mentioned previously, the lozenge is very nice, but I'm not sure about the fuselage. The tail section is fine, but I may paint over the rest using the decal as a guide, then overspray it as required. I think he tried to do the decal as the finished "oversprayed" look and it doesn't quite give the look I want - plus the wing section shouldn't be oversprayed, and the lower tail section is missing completely, so that will enable me to match all those sections to each other. I'm not sure that the "wrap" format will work either - we'll see....
I did mention these points to Doug, so hopefully future prints will be a little better - this was, I believe, his first try at these (It's also only my opinion, and others may find this exactly what they need....)
