Swiss-lever movements normally have the singature RAX under the balance, but some also RL like the pin levers.
Not all variants were actually made. Only those are listed, which are actually known or contained in current registers.
Example, year: signature; shock device
ca. 1970: RL, C2, Delaware Watch Co, Swiss, 17 Jewels; Incabloc
