Siskin fighters lined up at Hendon. First row, J8950, J8664, J8662, J8056, J8666, J8668, J8670 of No 29 Sqn. In second row is J8836 of No 43 Sqn. On No 29 Sqn's previous equipment, the Gloster Grebe, the squadron marking was four crosses. On the Siskin this was shortened to three. Thus the origin of this marking is not a mispaint of a Roman numeral XXIX. Photo from: Imperial War Museums
