[QUOTE=Retrosonic;149419][QUOTE=Magnus_N;149260]Just to set things straight. International sizes are what we use today, with heads and shells measured in inches, not centimeters. The older, European (?) standard is called metric. Metric heads are hard to find.
>>>>Sorry, but this is not so.
"International" size heads refer to the European non standard size heads of the late 1950s. The snare and tom toms were 12.5 inches and the bass drums were 21.1 inches. This is not "Metric", these odd sizes were (and still are) called "International".
This is completely incorrect. ---The German drum companies each chose their drum sizing based on whatever factors influenced them. Trixon used different sizing for the snares than Sonor, who used the same sizing as Tromsa, because Tromsa made heads for Sonor. Trixon used the Dresdner standard for snare diameter.There was no specific standard because until Tromsa and Remo started supplying plastic heads, there was no need-----you just lapped a new calf head on whatever hoop, was required. The sizes were based on metric measure but within that broad definition, there were many choices and no standard sizing existed , until the manufacture of plastic heads with aluminum hoops encouraged it. British drums,French,Dutch,Italian,Swiss and whoever else unmentioned had there own basis too.
