The example that I have described as follows:
Main component, a disc, with 2 rotating faces, each divided into months, one side labeled N, other side labeled S.There is a clear plastic rotating element to which discs more on them in a moment, can be attached.
Regarding the above mentioned discs, 18 in all, 9 marked N Latitude, 9 marked S Latitude. Of these, 6 marked N Latitude. have a 4 5/8" dia rotating element rivited to the main disc. These bits labeled 35 degrees through 85 degrees in 10 degree increments. Ditto for disc labeled N Latitude. The other 6 discs, 3 labeled N Latitude, 3 labeled S Latutude, running 5 through 25 degrees in 10 degree increments are plain, they do not have the above mentioned circular rotating part.
I hope my description clarifies rather than confuses. Might my example be an earlier of later model? Any ideas? My device is indntified as follows, on the main disc.

Thanks.
