Michael,
Thank you for contacting Answer Army. It is hard to actually tell exactly what model number you may have for this unit. It sounds like it has been used for many years. If you are needing spare parts then we recommend you contacting your local servicing dealer. They will be able to help you find the model number and let you know if any spare parts are available for purchase. Thank you again for using Answer Army!
