VIIC, one or two periscopes?
If you Google
type viic "two periscopes"
the results is many pages stating that "...The Type VIIC/42...These boats would have been very similar in external appearance to the VIIC/41 but with two periscopes in the tower ..."
So the VIIC/41 came with one periscope?

I can see two, one taller that the other. In fact I am converting a Revell 1/72 VIIC/41 to RC and it has those two periscopes. I guess one is for navigation and the other for attack.
So?
