As I remember, one of these older German pianos had nothing showing on the 
bottom of the block, and the other had very small holes, (maybe 2mm?) in the 
bottom, as if only the brad of a brad-point drill had been allowed to go through. 
 It has been some time, but my memory is improving with age,(which is weird, 
because everybody I know seems to be losing their's enough to disagree with
