Comments about the data

Remarks
strange: With an intermediate wheel (bearing A, Fig.3) between center minute pinion B and excentric minute wheel C the height was reduced, since only the center-second wheel overlaps the barrel (details see Langendorf 1233).

Example, year: signature; shock device
ca. 1955: Lanco, 1021, Swiss Made, 17 Rubis - LWC; Incabloc
