Anyone know where I can get window lock, or even a gearbox, for this obsolete system? it's 2 central hooks similar to a door and 2 end shootbolts. The gearbox is got a black plastic cover with 4 screws. Titled as Settanta by Nova. Spoke to Nova in Altrincham who i.d' d it as Settanta+, now defunct. Anyone out there got any NOS? Cheers Kev.
