Block & tackle spring balance

Hello,

Your balance resembles the S795-30 with a 30B strength option. One difference that you'll notice is that the metal cam in your t-lock shoe is open, unlike the 15-195 that the balance comes with. For this reason, you should also purchase the 15-195B shoe with an open cam to replace the ones that come with the stock balances by following the video below. Thank you!
