This one walked into my shop today. At fist I was excited... then I realized.... it's not a tourbillon. The carriage is fixed to the front plate with two screws. Any thoughts?

These are the discoveries that make watch collecting so much fun! Brun also invented a shock absorber mechanism that was used exclusively on watch movements imported, cased and distributed by the Depollier Watch Co.
