50p Aircraft No 1. Armstrong and de Havilland. Perf Shift

booklet FB53 pane UMFB47. Perf Shift to left.
Sales price: 10,00

The shift is only about one perforation and does not give a 15p right narrow band as the listed pane variation has, however the shift does put the 3mm band on to the perf - one of the risks of using a new issue service.

I also got this twice, as booklet and as a Machin variation. Selling below cost. Average perfs.
