Thanks for the detailed information. Sounds like you need an S795-34, with a stamp option of 34B. The 15-195B Open Cam shoe is sold separately. The video below shows how you can easily swap it out with the shoe that comes attached by default to these balances (the 15-195 closed cam). Let me know if you have any further questions.
