just a few words about my two mini ( that are NOT for sale , so if this is not the right place please move this post to the correct one ).
S = 15- 18 cm.( there is a small difference between the two balls )
G= 42 gr.
durchmesser = 39 mm.
shade = cream-white ( RAL 9001 )
H = 93 circa.
according to the first owner who bought them in 1963 ( he is an old and famous player from Sanremo : Michele M. , now around 80 years old ) these balls were given to the "publikum" players in the very early years of minigolf
( the first courses in concrete were made in Italy around 1959 ).
Michele was a very close friend of N. Wagner and received from him all new balls , being also the "chief-trainer" of the Italian team.
these balls are 100 % "temperaturkostant" : I have tried to heat one for hours ( keeping it in my hands , so with a difference of more than 15 °C between air and hands ) , but the rebound difference didn't change at all.
the reason of this is probably the material used : silicone ???
this is not the only example of a ball completely "heat-proof" : I have seen also some old MG with silicone, such as mg 18 ( vorlaufer with a small spot of white paint ) and mg 10.
these two mini were given to me ( as a gift ) in 1991 by Michele and are proudly taken by me in my collection ( I have begun to play at the end of the 1970s ).
just for curiosity : in the early 2000s during a tournament in the north of Italy ( Naturno-abt 2 ) ...
a famous Dutch dealer noticed these balls and offered me 800 DM for both .. I obviously refused his proposition and he went away quite upset ....muttering bad words in his native language .....
