I have this small container marked Sample Jaeger Balance and Escapement Pat# 2531966. It houses the following parts.
I was wondering if anyone could tell me what, if any LeCoultre product this would have came from. Or, is it some experimental part maybe.

I thought maybe it was an early ATMOS clock balance but it doesn't seem to look like them.

another view, Patented in 1950, shows an assembly for use in time clocks, but I cannot place the part in any Jaeger products
