John,
It was fitted from new at the factory, its on the Morgan MY22 price list .I'm not a small ;frame and long legged even with the hood up, its not always graceful but I can get in and out without too much of a problem (with the seat fully back) with that steering wheel. I'm sure either Morgan or a dealership might be able to get hold of the boss and wheel. The wheel has a really nice feel to it and finishes off the car for me, you hardly notice the incongruous auto gear stick as its lost in all the polished wood.
Although marked out of stock here is a link to the boss cost £550
