Your Bike is a Hercules and the model is Churchill De-Luxe. The year of the bike is post 1950, as prior to 1950 the front Dynohub had a bakelite outside plate and yours is steel! The date of your bike is stamped on the backside of the Dynohub or on the Sturmey Archer AW 3 speed hub. It will be the last two digits of the year the bike was made. Your bike appears to have a 23" frame for a person about 5' 10" or taller. The bike can look a whole lot better after you clean all the rust from the chrome and clean and polish the paint. The Vinyl seat appears to be in good condition. Hopefully, your tire size is 26 x 1 3/8, which are available in some bike stores or on the internet. Once cleaned up, the value of your bike can be as much as $300. Good Luck!
