Default 90 volt inverter for battery valve sets

Purchased many years ago from Geoff Hopkins, half assembled into a Maplin Ali box (Maplin p/n AB24 or maybe LF16), requires 6 volts (4 AA'a), the single sided A4 instruction sheet has full instructions. I have already fitted a pair of 'D' size battery holders to the lid, it just needs a 4 AA holder, wire, connectors and a switch, plus of course batteries and time, to complete.
The Maplin box is approx. 13.5 x 10.5 x 6.5cm but it could all easily be squeezed into a much smaller box

To make it easy 10 inc RM 2nd class postage.
