What is classed as collectable and what is not ?
Beauty is in the eye of the beholder, but generally any engine that is water cooled, made up to the 1940’s and is relatively pleasing to own and operate. Some air cooled engines slipped in, like the Bamford and a few others, but this definition will not cause most engine people any trouble. Non-collectibles really are those engines which by definition are too modern, not of stationary origin or are just not of any interest to collectors. There are no Lister engines that are not of interest, even up to the 1960’s with the D, the same goes for most Petters, all Crossleys up to the point where they switched to larger and larger marine engines, all Rustons up to the 1950’s, and a few after that, all Blackstones of single cylinder size, preferably old and oily and open crank, most Bamfords, etc etc. Note that in the smaller air cooled types, Norman, Douglas, JAP and Villiers all had early engines that generate a lot of interest.
