For motorcycles The number system is simply chronological, the letter designates the engine size. I don't know the industrial engine system.
So, "F" designates a (nominal) 100cc engine, the 1F was designed/released before the 2F which was released before the 4F etc. I suppose that they sold the 1F for a while as a motorcycle unit alongside the JDL autocycle engine, only releasing the 2F when the JDL ceased production.
There are often gaps in the numbering which probably shows an engine that was designed but not sold e.g. 3F & 5F.

Hello Don,
According to Jack Sizer's Villiers book, the 1955 type 28B was an industrial engine of 353cc, and a two stroke. In 1974, Villiers produced type C28 which was again an industrial unit, a four stroke of 256cc.
Villiers' numbering system is an enigma to me. We do have a couple of New Hudson Autocycles with Villiers 2F engines, and I just love the sweet way they run. The 2F is single speed, but the 1F is 2speed. It must have made sense to someone at the time.
