OK I think 50Hz would not be a problem my electric clock would run a little slower.
So I think 50Hz for the most part would be compatible with my 60Hz,
However, could I get 110 volts AC out of a UK Lister generator set?
Thank you

The frequency output by a generator is determined by the number of poles and RPM. The number of poles is determined by the design of the generator; 2 or 4 poles is most common, sometimes 6 or more poles are available. (There is always an even number of poles). The formula is
Frequency = #poles * RPM / 120
So for USA 60 Hz, you need a 2 pole generator at 3600 RPM or 4 pole at 1800 RPM.
For GB at 50 Hz, 2 pole at 3000 RPM or 4 pole at 1500 RPM.
Lister CS or CD are going to turn around 650 RPM, so I don't think it's going to work as direct drive. (I don't know of anybody who makes a 12 pole generator to run at 600 RPM). Lister did make later engines that would run at 1500/1800 RPM and could be used direct drive. Most people that I know of use belt drive on a CS with the proper pulley sizes to make it work. A common situation is to run a serpentine automotive belt on the flywheel (no grooves) and use a proper size groove pulley on the generator.
I seem to recall a direct drive Lister CS but the output was rectified to DC to charge a battery so frequency wasn't important.
