Unusally seen so-called: WHW- (ie. 'Winterhilfswerke'-) related miniature harmonica entitled: 'WHW' that comes in a moderately used condition

This is a neat - and actually unusally seen! - so-called: WHW- (ie. 'Winterhilfswerke'-) related miniature harmonica entitled: 'WHW' that comes in a moderately used condition. The tiny piece - only measuring 3,5 x 1,3 x 1,4 cms. - is constructed from red-coloured wood having two chrome-steel-based decking-plates of which the upper-piece shows the engraved text: 'WHW' (as can be seen on the pictures). The piece - which is still fully functional - shows some minimal (rust)staining but comes in a wonderful- (and naturally still functional!) condition. Simply a nice occasion to acquire an unsually seen WHW- (ie. 'Winterhilfswerke'-) related item!
