Zincs for a Ford Lehman 120 Watermota Sea Lion

[BuoyOBuoy]

I have a 1979 Albin 34, purchased last year and unsure of when the zinc(s) had last been replaced.
I think there is one on top of the heat exchanger but could there be more?
Anyone who is familiar with this engine, I would appreciate your comments.
I have searched through all the threads on our Forum and unable to find one that matches my request. (Let me know if I missed one.)

A FL Lehman 120 usually has one anode on the large heat exchanger, and may have smaller anodes on the lube oil and tranny oil coolers. The smaller coolers which were sold as cupro-nickel could come without the port for the tiny pencil zinc. I never bothered putting zincs in the two smaller coolers.
