Vintage Ricoh 35 Deluxe best rangefinder film camera

This is a vintage Ricoh '35' Deluxe rangefinder camera that was made in Japan in best 1956. It offers manual focus with the help of a coupled rangefinder and has a fixed lens with a 45mm f/2.8 Riken lens. The camera is not working properly as the film advance lever is stuck, but that seems to be a common problem hopefully a simple fix. From the little research I did, this was one thing that seemed helpful

"It's often possible to free these up by removing the bottom plate (not difficult, just three screws)and gently moving the various levers, gears etc and carefully applying a little lubrication where appropriate."
