Model Steam Turbines (Classic Reprint): How to Design and Build Them; A Practical Handbook for Model-MakersExcerpt from Model Steam Turbines Steam turbines may be divided into two classes: the impulse or action type, in which a jet of steam or ? uid at high velocity impinges on a number Of vanes or paddles fixed around the rim Of a wheel free to rotate, and the reaction type, more generally known as Hero's Engine or Barker's mill. Both these types are pretty familiar to us from our Childhood's days, in the windows of the toyshop, and no doubt in many cases

Excerpt from Model Steam Turbines

Steam turbines may be divided into two classes: the impulse or action type, in which a jet of steam or ?uid at high velocity impinges on a number Of vanes or paddles fixed around the rim Of a wheel free to rotate, and the reaction type, more generally known as Hero's Engine or Barker's mill. Both these types are pretty familiar to us from our Childhood's days, in the windows of the toyshop, and no doubt in many cases (the writer's also) formed our first steam model. They are illustrated in figs. 1 and 2, and frequently appear in patent specifications, though, of course, with considerable modification. In order that the principles on which these machines are designed and for which they depend on their action may be thoroughly understood, the following elementary mechanical considerations are necessary.

Good Fit Out of the Box
Size: 9, Color: Black
The shoes came with the correct size and is a good fit. They were originally pretty stiff, but are much better now after breaking them in. They look good. but as other's have said, they are made of synthetic leather and in my opinion have kind of a plastic look to them. The quality is good with ridged rubbber soles. I thought they were kind of expensive, but then again I haven't purchased these type of shoes in a while. A family member told me that if they were real leather, they would have been a lot more expensive. For what the shoes are I would recommend the purchase.

I wanted to love these
Size: 9, Color: Black Leather
These are very good looking in person, especially the buckles and the pop of red on black. Alas, I have another pair of Marc Joseph shoes to compare comfort and fit, and this pair simply hurts my feet.
