I agree with the date. It's definitely prewar because of the use of the Telma shutter. It's not one of the earliest models, because of the shiny chrome pop-up viewfinder, the shutter release on the top deck and the sliding door over the frame window.
This is in excellent condition. I generally am skeptical of claims of "mint," but this one is as close to mint that I've seen. In any case, it's in excellent condition.
