Engines by Piece Parts and Assemblies

The PW203 and PW201 models c1946-49

Bowman Models Ltd of Luton were in no way connected to the Dereham-based company established by Geoffrey Bowman-Jenkins in the 1920s. This company, which was actually Piece Parts and Assemblies, had purchased the Bowman name after the second world war, much to the upset of GBJ. PP&A were involved in manufacture of aircraft parts during the war and were looking for other areas to expand into after the cessation of hostilities in 1945. The fact that the Luton engines featured aluminium in their construction may have been more than a passing coincidence due to their wartime activities. Luton Bowman products should not be confused with their Bowman counterparts, but they are a collectable 'marque' in their own right.

More information about Luton Bowman can be found at the Bowman Circle website here.

Four stationary engines were made: the PW201, PW202, PW203 and twin cylinder PW204. The hard to find PW202 was an overtype version of the PW201. The PW203 and PW204  were the largest and are very well made engines, featuring a larger cylinder complete with oiler and regulator. It also featured the 'BM' letters on the firebox. 

Four excellent boats were made: the Seajay, Snipe, Swallow and Seahawk. The Seajay is fitted with the superb valveless Bryant engine.
