Yes FK, in the Type VII like U-96 (Das Boot) the attack periscope is in the control room and goes up & down as asked in the beginning of this thread.
The attack scope is in the conning tower, and is normally of the fixed heigth type, i.e. the big one with seat and pedals controlled by the commander. But not all Type VIIs had that periscope, some built on certain yards or when moments of shortage of equipment had also as attack periscope another up & down one (Installed in the conning tower), which was identical to the observation one except in the outer head, which was again reduced in size, as it corresponds to an attack one.

In fact, the fixed heigth periscope was just a housing with prisms, seat and pedals that replaced the lower end of the periscope. On it you could install the upper part (i.e. the tube that went up and down with the head) of any attack scope you preferred.

Type IIs had one scope in the control room and another in the conning tower, but none was of fixed heigth type (as opossed to how it was modelled in SH3).

Type IXs and XXIs had a fixed heigth and a standard observation one, both in the conning tower.

Type XXIIIs had only one, in the conning tower, and it was not of fixed heigth.

Type XVIIs had both in the conning tower, and none was of fixed heigth type.
