As promised - since the start time of FS Group Build do not agree with the start time of my model - I show my share in Battle of Britain project here.
This is an old Secter 1/48 model with Eduard PE partss in the cockpit and few details added: Venturi tube, side glasses in the cockpit doors, undercarriage actuators and modified Pitot tubes.
The model shows an a/c of Mag. Mario Bonzano from Corpo Aereo Italiano, Ursel (Belgium), November 1940. The effect of heavy chipping paint was done using “salt technic” - I hope it looks a little bit similarly on the model.
The photo of the real plane (from Internet/for discussion purposes only)
I was rather skeptical of your placement of the chippng until I saw the photograph. Man, you nailed it ! it looks exactly like the photo .Beautiful job and I admire your skills.
I love weathered planes. You are right about what may have happened to the finish. At the time of year of the B of B and the location of the aircraft, there probably was moisture under the tarp and it baked in the sunlight a number of times. Add to it the the speed of the a/c while in flight and you have a “sand blasting effect”. Just the same great job!!!
