He constructed the Invicta at his works at West Orchard, Coventry, commencing in 1913. The machines were fitted with 269cc Villiers two-stroke engines with petroil lubrication and a chain-driven magneto. Two models were offered; both had Druid forks. One was belt driven, the other had a two-speed Jardine gear and chain-cum-belt drive.
Tragatsch suggests that the Invicta marque continued until 1923.
There was an earlier Invicta built in Clapham 1902-06, and there was also an Italian marque of the same name.

I am helping another with a project and he has a Invicta with a JAP engine. The numbers are LYB.
I understood that the LY would designate it as the 550cc model engine, and that the B would be the year. I cannot find any reference to B having been used by JAP to designate a year, would you have any suggestions as to what engine this might be.
I am working on getting some pictures. The bike I have not personally seen as it is on the East coast of the states and I am on the West coast. However the person will forward some pictures when he gets a chance to take them. All I know is that it says Invicta on the gas tank and has a carbide light, pedal starter, chain drive, Armac carburator, I believe a three speed tranmission, single cyclinder side valve, approximately 30cc or so from what the guy says. Sorry this is all that I know currently
