Anyone has good weight data on Ejection seats?

[AeroFranz]

I've been looking for data on ejection seat weight and was surprised to come up empty-handed after a good thirty minutes of looking in the obvious places. The Martin-Baker site is spectacularly silent on any specification worthy of note, such as dimensions and weight.
I'm particularly interested in the latter. Does anyone have decent weights for lightweight ejection seats ? Thanks!

I seem to remember that some early Martin Baker models weighed around 80kg. Can't find sources for recent models.

Thanks for the help, i'm still surprised there isn't more information out there.
i found a few weight figures for older seats here:
