Well, some more information about that dismantling dummy
would be helpful.
I found out something about DN200:
Most Google-hits deal with Greman tube
specifications for sewage water systems.
DN200 = 200mm diameter
(also 200mm connecting diameter).
So may be this dismantling dummy is some kind
of a tool... I'm sure you don't need it for your Berg... :lol:
Anyway, no idea if I hit on it, if not, Json just move this
post to The Lighter Side...
