This is a chin rest that came with a used viola I recently purchased at a Shimamura Music store. I replaced it with a different chin rest after the purchase, so I'm selling this one. I will ship it as is, in the detached condition, without disassembling it. When tightened the most, the distance between the corks was approximately 37mm. Please forgive any errors, as this was measured by an amateur. I don't know much about it, so I don't know the model name. Thank you for looking. #ViolaChinRest #ForViola #ForViola #ViolaChinRest #ViolaChinRest #ViolaChinRest
