Thanks
I'd like to pick up a nice early 1900s-1930s camera just as a representation of the period
As someone who has quite a number of pre-WWII and WWi cameras I ahve to say only you can choose where to start.. I have many Houghton cameras dating from an Alliance Roll Film Camera Co Ltd. thats a 5x4 camera taking 110 roll film, made between 1898 and 1905, through to an Ensign Selfix 820 6x9 120 camera from the 1950's, and then 3 Houghton field cameras, Quarter , Half and Whole plate as wellas a quarter plate Dallmeyer Press Reflex (made by Houghton and usually sold as an Ensign), plus a Houghton King enlarger, Ensign safelights and Contact frames to 12"x10".
Most representative of the inter war years is a 120 folder, if you want to use it don;t make a mistake buying a 620, and there's a huge choice I see them (lower to mid range models) at the camera fair I go to ofte for £10-£20 ($13-$26) alhough better nad more desirable models can sell for much more depending on their condition.
I'd also suggest getting an Iconic box camera, age is difficult to tell as essentially the mae madels were made into the 1960's by Kodak both in the US and UK, they disappeared with the introduction of the Instamatic.
