1970's RAF Wing Commander's Pennant/Flag

An original early 1970's R.A.F Wing Commander's pennant in very good service used condition and still retaining good strong colours, of cotton multi-piece construction with no moth damage, the white coloured spine is a bit grubby/stained from usage and has a couple of rust marks from where drawing pins were used. Along the spine are various ink stamps including the correct 4B R.A.F stores prefix, 4 denoting Aerodrome equipment and B flags and visual signalling equipment, the rope's loop/toggle has been removed possibly to display behind glass ?. This pennant was discovered alongside the RAF Squadron Leader's flag which is also listed for sale (code 51007), both service used and rather intriguing, wish I knew their history. Measurements - 36 inches to point, 27 inch along spine (approx. 91 x 68 cm).
