Proffski -
Where did you put the long-haired wool, the BAF and the sculpted foam?

Apologies for not responding to any of these posts, someone died in my family so I have been preoccupied elsewhere.

I am still working on reconstructing Kefkit 3 into Dr Baileys Transmission line. But in the German leaflet there is a version of it made out of perspex. It doesn't seem to have any long-haired wool in ...
