Salvation Army Centenary on the Isle of Man, 15 February 1983. A not seen before cachet was just obtained. It has a similar picture to SA 19.7, but the cover & print is smaller and color is different (purple). Produced by Ramsey Philatelic Services (No. 138), and must be in limited quantity (since it’s not seen been). Single William Booth stamp, which is seldom in itself.
