What balance assembly do I order?

[Lc130]

The movement is a bifora 115/1. I have a bent HS which I'm not skilled enough to fix.   Ranfft describes the /1 as "suffix /1: lever banking by cock instead pins"

Cousins lists parts for 115 and 115.1. Is point one the same as slash one?

under 115.1 they have "Balance Complete, Ordinary, Bifora 115 721"

under 115 they list these below

 

Which is the needed part?

Thank you

Charlie

Hi Charlie,  Identify the shock protection system.

Failing a comprehensive overview from one of our experts, I'd be tempted to order the top one. At 6.95 it's not a big risk, and you can interpret the description "Balance Complete, Ordinary & Shockproof" as meaning a universal version.  I checked Ranfft, and all the variants of the Bifora 115 have the same balance staff number listed, so whichever you buy, it should fit.

The other option is to give Cousins a call and ask them. They are reputedly very knowledgable and helpful.

There are different versions of anti-shock-device fixing-springs shown by Ranfft (Bifora Bishock, Rufa-Anti-Shock). Which one do you have?

If the shock system dosn,t look the same as Dr ranfft shows.

Post a pic of the piece you got, for identificarion.

Beats me C, it is the same Dr ranfft displays and is called bishock, have never worked on one. Lets wait for advice to come in, may have to invite master OH or nickelsilver, clockboy for help.
