OK I picked out a subject at random, and wish it was something a little more involved than a simple bike pump. However, I will do it anyway. The pump I have is made by Marwi, This is an American Company I had never heard of, until I went to a sale, where I saw this pump. It was pure fate, as I had gone to work on my bike, and noticed that my front tyre starting to go flat. I had been given the bike recently, and there was no pump with it. I was going to buy a new one, but this was too good a chance to miss. I paid the enormous sum of thirty English Pence! The ump was bought with no guarantee, but at that price it was a gamble I was willing to take.
The first thing I did, was to attempt to fit it to my bike, but there are no fittings on them nowadays apparently, so it lives in the cupboard under the stairs. This is a suitable place if I need it when I am at home, but not so good if I want to use it when leaving work. I will fashion some simple Terry clips, fixed to my crossbar with Tie Wraps.
The pump is what seems to be a standard sixteen inches in length, and is the usual tubular plastic construction. There are some shorter pumps on the market, with a Tee shaped handle, but mine is the old basic model. When I stripped the pump down (As you do) I found that the shaft was steel, and the piston was rubber, this pump is single acting, meaning it compresses air only on the "Push Stroke". There is room in the handle for the short hose for fitting to the tyre valve.
The pump is quite a few years old by the looks of it, but it still has good compression, and weighs virtually nothing. I have no idea how much this cost new, it was probably given away free with the bike. All I know is that is was a bargain to me, and I can see no reason why it should not last me for many years to come.
I hope you enjoyed the review, not a very interesting subect, but all the more reason to write one. Have a go at doing a boring subject yourself!
