Gruen Authority

Gary, I should have been wearing my glasses yesterday evening. Correct, cal 843 is 6 ligne, also my source does not show an 8 but a 6.
OK, this leaves no number to be assigned to this particular movement for now. Are there more 7 3/4 or 8 ligne movements than:
103 -> Louis Cattin
139, 1396, 1397 -> (Marc Favre?)
615 -> (different supplier)
695, 696, 697 -> (much later)
857 -> (Louis Cattin?)

Dan, I don't think that these movements are based on Cattin ebauches. He did not have a workshop doing this, just assembly. These movements will be based on different supplier ebauches, LeCoultre, FHF and others are likely.
It still can be coincidence that Cattin is using the same ebauches as Gruen, but I think there is a high probability that Cattin supplied to Gruen. There is no proof yet at all.
