Nutloose,
When you say MOD surplus do you mean it is or was available to purchase? If they are BAE should buy them and offer to refit GR4 with them as an update, far superior to the original.
Indeed they were, the last one went for £25.00.... which is pittance, had it apart already to see the quality of the parts.
I intend to rewire a plug onto the base plug, possibly replace a couple of the switches with some ex MOD top hat ones I have, then connect it up to a knackered Gaming joysticks innards........ shouldn't wear out any time soon
Thank you all the help and for the replies, I take it now it is as said
TYPE
