Ahhh yes, of course
D9041 was very much one of those Graham-White built 'K' models supplied to USA.
The initial batch of 33 aircraft were delivered to Issoudun in October 1918 (tests had already taken place with 6 Parnall built ones in July) and 12 more in November. All further contracts were of course canx with the Armistice in place.
The only problem which remains is why the seller says 102 Aero Sq.
I am pretty certain it did not exist at Issoudun since it was not part of the 3 AIC
Come to think of it, is the last digit in the Issoudun code 0? All photos I have seen of the Avros show them having codes in the 1600 or 1800 range.
So this one is 18xx.....
