There are three styles of spinning wheel in this picture. The leftmost is a solid oak Beaver wheel - a North American design, with twin wheels and treadles; this makes the wheel very fast to spin on. This wheel was handmade by a very skilled craftsman wheelmaker, James Williamson of Timbertops in Asfordby, Leicestershire.

The middle wheel is a modern mass-produced wheel in beech, made by Ashford in New Zealand – the Ashford Traditional. These wheels are very popular with hobby spinners and, although not as fast as the Beaver, are robust enough to be used for business purposes.

The rightmost wheel is a traditional sloping bed design, maker unknown. This wheel was 'rescued' from a junk shop, and needed a little work to restore it to working condition. It was most probably made as a project by a woodturning enthusiast, within the last 25 years or so. (Unfortunately, the picture is somewhat dark - see below for a better view of this wheel.)
 

Here is a better view of the traditional sloping bed wheel in action.

This is a motorised (electric) spinner made by Ashford in New Zealand. The unit is comapct, and runs from a mains operated (sewing machine) motor. A foot switch can be attached to start and stop the motor, and the speed & direction are adjusted by means of the switch and knobs on the front panel. These units are useful if you are unable to treadle for any reason (as Lesley was, recently, after an operation). However, they are very expensive, and too slow for business use - Lesley is able to spin faster on an 'ordinary' wheel than the motorised one will allow!

This is a closer view of the flyer unit, where the twist is put into the fibres, and the yarn is wound onto the bobbin. This also illustrates the drawing out technique.

This wonderful contraption is called an umbrella swift. It is used to hold a hank of yarn whilst it is being wound into balls, and is a boon to the spinner's husband (or wife)!

And here is an illustration of the technique of circular knitting. There is no sewing up of the garment to to at the end, but the garment seems to grow very slowly when knitting in this way.
