Is this the U-47 Type VIIb? There is also a 1:125 scale Type VIIb which is not a cutaway sold as the U-99. The outside is good, but as a minimum could stand having some of the railings sanded down to lighten their too-thick appearance. The limber holes need to be opened, but that shows that there is no pressure hull. Nautilus Models made a resin replacement conning tower, deck gun, and PE set to kick it up a notch.
The interior is ficticious. It comes nowhere close to portraying the cramped nature of these boats. No pressure hull, no flood tanks
I believe the cutaway U-boat shown in FSM within the last year or so was a Type XXI, which had been extensively reworked
