Hi All, Though there have been alternatives suggested and made over the years, the original Moseley as evidenced by Chris' photo of one from my Type 75, is multifold. While the tube and plug system the Moseleys had was a bit primitive, they were flexible as the Schrader valves are not, as was noted, with the potential to have hard points. These hard points can be uncomfortable but also have the potential for wear spots. As a whitewater paddler(Open Canadian canoes) I'm familiar with the float bags we use in our boats. These are both mouth or pump inflated, flexible and durable. So no hard spots or wear points.
The Purves ones were quite good and matched in form the Moseleys quite well. The material is less flexible than a simple rubber inner tube, which is important.
Further, the originals though a simple idea, were far more than a simple stadium cushion. The outer could be inflated hard, while the inner much softer creating a bucket seat with support on the sides and front. That's why Moseley used the U shaped outer tube and complete serpentine inner tube. Further, it is important to keep them located and that is where the binding straps come in.
Tony, I'm assuming for your Ruby rear, you would want what I have seen of double Moseleys, a tube forms a U on the front and sides of the seat bottom, with two complete serpentine sections in the centre. Is that correct.
I'm encouraged that there is interest here, as I've also had interest from folks in the Frazer Nash fraternity. I've always thought that Moseleys and the other firn which produced inflatable cushions, were a great concept and with modern technology could be made even more durable. I have a tent made by a company named NEMO which uses inflatable tubes to keep it erected and I may contact the maker to learn more about his suppliers. He had worked with NASA on some of his designs so there may be a good source of durable tubes there.
