Wanted Early McCoy 40

I am still looking for an early Red Head McCoy 40, the one with the recessed exhaust web. Will trade for Red Head 40 with flush exhaust web, or I have a lightning bolt 40 I could also trade. Both have excellent compression and are in excellent overall cosmetic condition. Can provide pictures, if interested.

These engines are too hard to find and only avaialbe for trade for the one I am looking for. They are not available for sale. This early model 40 is all I need to have a complete collection of the post 1958 Red Heads; will pay reasonable top dollar, if don't want to trade.

Thanks
