Spitfire Mk.I underwing roundels during Dunkirk evacuation

Recommended Posts

Hi All

I'm currently building No. 222 Squadron Spitfire Mk.I (ZD-A P9317) from the Battle for Dunkirk. Soon I'm gonna start placing decals and I have a problem. If my knowledge about roundels is correct (and probably isn't) the roundel placed on the black (night) painted underwing shout have yellow outer wing. The issue is that DP Casper's decals don't have it. I was trying to find a photo of that plane but I haven't found any.

Can anyone help?

Cheers

Dominik

The yellow surround is a bit unlikely; the order for it wasn't sent out until June 4th., and, on June 7th., it was followed by a further order that the undersides were to be painted with Sky.

When the black port wing (only) reappeared in November 1940, so did the yellow surround for the roundel.

I don't know if the colour scheme of the restored Spitfire P9734 would be relevant, but the pictures on Flickr are worth a look for reference if nothing else.

Edgar, the information you've given is surprising as I remember a few photos of Spitfires with black and white undersides with roundels having yellow surround from the Dunkirk evacuation period.

2wheels great photos! Wish I had decals to build her.

Dominiks: The problem lies in knowing whether the photos actually belong to the period claimed.

2Wheels: in Andy Saunders book on the restoration of P9374, the matter of the yellow surround underwing is discussed on pages 117/8. He quotes the date of the 4th June, signal X479, but goes on to say "...there is evidence that this may have already been put into effect prior to the date the signal was actually issued and that operational squadrons were clearly applying the change "in the field". Therefore the signal simply made it official across the entirety of Fighter Command. It was thus decided at the yellow band should be applied to P9374, although naturally it is recognised that this may be in error. It is, though , a best guess - albeit an educated one."

It would have been good had he expanded further on the words "evidence", "may" and "clearly".

These help?

You can match the shots together by the staining at the wingroot - definitely both the same machine. Unless it's orthochromatic film and the yellow is invisible on a black wing, I'd say leave the yellow rings off.

Vulcanicity thatnks for great photos. For me it's clearly visible that there isn't thye yellow ring underwing. It's not orthochromatic as yellow ring is clearly visible on the fuselage as light colour.

Edgar thanks for making it clear . Unless I have good photo evidence I'll leave yellow off from now on (nontheless I remember photos desribed as Dunkirk period - later I'll try to find them and post here).

Thanks for help!

Cheers

It was a post-forced landing shot, so I imagine the hydraulics were shot through!

I've always been intrigued as to the colour and purpose of the band under the nose of this aircraft-some sort of flight leader/CO marking perhaps?

Spitfire flaps are operated pneumatically, not hydraulically, and held down (against the airflow) by positive pressure. If the system fails or is damaged in flight the flaps should both be forced up, avoiding asymmetric operation. On the ground the flaps were raised by a compression spring 'enclosed in a cylinder and connected to the flap' according to the pilot's notes.

For whatever reason, and the fact that it is a post forced landing photograph must be a clue, the aircraft looks, unusually, to have been parked, flaps down

Hi

I have often wondered if was an indication to groundcrew that 100 octane fuel was to be used

Just one more question about the a/c. The code letters on starboard side should read ZD-A or A-ZD (looking at the fuselage)?

Well unless there is a pic of the aircraft it's anybody's guess. There was no agreed standard at the time.

Going back to the question of yellow surrounds for port underwing roundels on Dunkirk-era Spitfires, there's a pic on p.64 of Osprey's "Spitfire MkI/II Aces" book showing Bob Stanford-Tuck and Allan Wright in front of one of 92 Sqn's Spitfires. The aircraft still wears the GR unit codes (before the change to QV in the June 1940 timeframe) and apparently has a yellow surround to the port underwing roundel. I haven't found the pic online and I don't have a scanner but it's there...honest! :)
