copper clad range made by mallable range co. model 4723-c-g

this stove burns both wood and l.p. gas the tank is empty but I know that the wood side works to heat the kitchen portion of the house and my mother -in -law used the l.p. up til her death at the first of the year. The tank ran dry a year ago and she decided to wait til spring to fill the tank . she past before filling and we just go the keys to the house . I'd like to keep using it but  have no idea where to locate parts if needed. any information would be welcome.my guess is that it's from the early 1900's because I remeber my grandmother having the same style range in her farm house.I can not send a pic as my coputer is not able to scan
