Phil, you prefer cash or Paypal ?
I have four unpainted rainbows. A 5000 with brown knobs, a B4000 with brown knobs, a 5110 with brown knobs (the 5110 was never sold unpainted so this not original) and a 5002 with white knobs (looks terrific but not original again). I also have three more empty cabinets and 2 or 3 chassis in a box. The plan is to paint one of the spare cabinet with the original cream white for the 5110 and use white knobs (I have a few spares left). The 2 brown knobs will then go on the 5002 but I still miss one. I thought I was good at mathematics but those babychamps knobs got me.
