Could anyone tell me what the mass is of a SR2 directly coupled to a Hoffberg 4kw 220V alternator? This is all mounted on a 76mm channel iron base. I don't think you guys got the Hoffberg, it is a South African thing, but I guess it is pretty much the same as a ST head. It has the 24V starter windings included. I need this info for shipping purposes. Thanks in advance, Peter
