A friend of mine found this at the back of his shed and gave it to me for quite a nice price. It is a Mamod SP2 stationary steam engine which, from the years my friend has had it, can be dated around the 1990s. This is a problem with the SP range. They are not really yet antiques since Mamod are still producing them. Therefore, although my SP2 engine is actually over 20 years old, because of the fact it is still produced today, they are not rare yet. One thing for sure is that an engine in such good original condition that is over 20 years old is quite rare!
