Please note - there are 'pre-cleaning/restoration pictures  !

Note the extra LH ring and extra pad under the LH D#/A#  'banana', different C#/G# mechanism, and the added low Ab/Eb key sticking out of the LH 'pinkie' cluster.  

This is the Pruefer 'A' [bottom] with trusty Bb B&H Edgeware [middle], and a nice little HP 'C' Besson [top], don't they make a lovely trio.....
