Bar-x £4, £6 and £15 rom sets

Hi does anybody know or have the above rom sets for the super bar-x series?

I've currently remade the £5/£8 and £10 layouts and was wondering if these other ones are about. I've seen the £6 machine down weston so i know its real.

There is about 95 different sets on planet emu but that'll take months to trawl through, not even sure the £15 set will run in the current emulator as the £25 above ones don't.

thanks in advance Vectra666.
