Paul, extraordinary as usual! And all in 72 which makes it even more impressive. I thought the OOB Airfix kit was pretty well done but you have made some major improvements. The front end/cowling work looks excellent, really like the vents you've created for the underside as well as all the upgrades to convert to the B.E.12. I know you had to spend some time to make that front end fit but fit it does... and looks like it was intended that way from Airfix. Also, really impressed with the rigging (I'm a stretched sprue guy but can sure see the benefits with your technique), the cross over line on the upper wing and the double lines throughout look great and really add to the interest and realism of this build (those double lines ain't easy to do and it looks like you've nailed it!). Painting is first class and I guess I could go on and on but I'll wait until you've completed it.
Always enjoy seeing what you'll come up with next...
Take care
Scott...
