Identify a RCA70 vs RCA 60 Simpson Lawrence Gypsy

[cadmus]

I am trying to determine if I have a RCA60 or RCA70 gypsy on my S/L HySpeed windlass. I can see no stamp or markings but might not be looking in the right spot.

Is there a stamp or marking and where would it be?

Is there a way to differentiate these by measurements?



Thanks in advance for the help.

Hi Pete,

Count the pockets.
6 pockets RCA60
7 pockets RCA70

Both gipsies are bronze.

Here i tore apart the office looking for my good calipers and was preparing to polish the entire thing looking for the part number stamp.... egg on my face.
