Dear friends,  for a good friend of mine we are looking for a spring
like: 1 Feder (=spring): 85 mm breit x 1 mm stark x 5 m lang (=long)
[3.35" wide x 0.039" thick x 196" long].  Where can I find such a piece?

With all my best wishes,

 [ It seems like a "clock spring" for a big spring-motor, as in a large
 [ musical box.  If the core (axle) is 25.4 mm (1") diameter, then the
 [ outside diameter of the tightly coiled spring is 84 mm (3.3").  What
 [ sort of shop or firm could fabricate a big coiled spring like this?
 [ (The same equation is used to compute the diameter of a 10-tune music
 [ roll.   ;-)   -- Robbie
