I do think the small around one was for the oil. My cutaways show the mk9 so don't know if the large oval had some in it.
Kinda funny, I have a picture book on late marks 7-24 and another one on early marks 1-2. Somehow i missed the mk5. My spitfire book (Alfred Price) has low res pics so not the best for referencing specific details.
Been slow but steady progress.
Added the underside blisters and ailerons, servos are mounted now.
Since the mk5 was the first to main the 20mm armament I gave it a shot.
I wanted them removable for tranport and hangar damage avoidance. I mounted short carbon tube into the leadjng edge for the base. Used magnets to hold the barrels in place. Mounted another short carbon tube into pine and turned to shape. I will add tiny carbon tube for the protrouding barrels once painting starts.
The Eflight retracts were next but I need new gear legs. The legs are too long and worse, the leg coil of the stock gear sits right at the formers and support for the lg blocks. I will buy some 5mm music wire to make new legs...or buy some small oleo legs.
The 15cc engine was installed so I could mount the cowl and finish forming/shaping the nose blisters. I cut a disc to help align the cowl to the spinner that is still on order.
Next was to get the pilot into the office. I discovered the existing vac formed headrest and "office" that was installed were way too low. Since I only had a bust figure to man the office, I decided to rip out the cockpit and sealed it over.
The canopy is badly frosted. Thought it was caked on saw dust and such but after soaking in water and trying to clean it made no difference in the look. A stop at wally world for some future floor polish has helped. Still not great but better than before.
Need to mount gas tank, fuselage electronics and this will be ready for painting.
