Interesting roundel on that Yemeni Hind

It looks very similar to Dominican Republic roundel (no, this Hind is not Dominican, of course). Also I see some insignia on its tail.

Always looking for something different! Photo taken in 1952 in Texas. Italian Curtiss S2C-5 with a very strange roundel.

Could it be that this is an ex French aircraft handed over to the Italians with a makeshift roundel added to it ?

This is very doubtfully. The Italians used SB2C5 aircrafts in years 1950 – 1959 (42 examples). The French used SB2C4 and SB2C5 in years 1950 – 1958 (110 examples). As you can see, the years are the same – so, those aircrafts were purchased by each country separately.

Besides the Avro 504 & DH-4 identity, can any other information be had by looking at this photo?
Any idea what the nose art may be?
Does lack of National insignia indicate anything?
Any idea if the photo was more likely taken in USA or overseas?

1) For nose art look this link (wait for some seconds until the image will be opened in separate window over linked page):

This is emblem of 166th Aero Squadron. Its history described here:

2) The national insignia are in places – see the stipes on the tail rudder. Also in that period US planes had the roundels on their upper wings and lower wings (see the example below). So, it is all O.K. with the insignia:

3) I think, the photo was taken in the United Kingdom during American Expeditionary Force (AEF) training, or in France, during their operations. But I am not 100% sure about exact place.

Hope this helps.

Is it one of the ex Egypt airframes ?

I do not know, if that airframe is ex Egyptian, but all titles near the instruments in cockpit are in Hungarian language.

Also C. Lindberg with Klemm aircraft are on photo here (see the bottom of page):

“In the autumn of 1927 Hanns Klemm was visited by two Americans , George Kern and Willibald Seypelt who bought each a L20.”

Even in this case these American gentlemen could take 2 factory-fresh Klemm aircrafts directly from the production line, having the permission from Herr Klemm; and those planes could have the serial numbers only. Immediately after the purchase of aeroplanes, these men “began a tour of Europe”, which ended in the end of January 1928. And after this they could go to America immediately, and their planes could not have any German registrations during all this period.
And in March of 1928 H. Klemm had the business trip to America with other 5 examples of his plane.
I seem, this version looks plausible.

I’ve never seen a photo of the assembly line and wondered if anyone has seen such a photo.

Yes, even here, in Russia, we saw very few MiG-15’s photos during production process until today. But I can show at least 2 photos here:

1) The beginning of MiG-15‘s production on State Aircraft Factory # 1, named after J. V. Stalin. Kuibyshev town, 1949:

2) The drying the paints on MiG-15 fighters in special drying chambers. State Aircraft Factory # 153, 1952:

Moroccan Fury’s
P.S. Can anybody shed some light on the markings?

Possibly, Your images show simplified version of insignia, without crown and red circle. Probably, such version was used on “frontline” planes, heavily camouflaged (instead of natural metal aircrafts, which were used as trainers or “parade planes” in rear mainly). Also note – the sideview shows the 1978 machine, Your images show earlier time planes.

No, these Saudi planes have the tails, not similar to Piper Cub/Grasshopper/Super Cub family tails. These are the Aeronca 7 “Champion” aircrafts exactly, and, most probably, the 7BC version – compare those airplanes with the plane on this link:
