I recently aquired this partial unused wing from the UK at a very reasonable price. I was so excited to find it that I didn't pay attention to the lack of holes for the indicator lights on the front panel. I presume this to be a series II wing? I plan to use the wing on my IIa but hate the thought of ruining a near perfect series II wing by drilling another hole. I'd be willing to swap for a IIA wing in excellent condition if anyone is interested.
