You always find a loophole don't you?
Well the drawings in some of the ST magazines are sometimes quite imprecise, for example some of the Defiant's drawings are based on outdated material, when she was supposed to be some kind of supersized Runabout "Hot Rod"
Specs for the Emperor
(From Klingon Academy)
Information on the Klingon Heavy Battlecruiser is extremely limited, although it is thought that her weapons loadout will be slightly less than the discontinued BerÃ¢â‚¬â„¢taaÃ¢â‚¬â„¢s armament loadout for this vessel. Her class designation is the Emperor class (VoDleh). This vessel, to some degree, was designed by Klingon naval engineers to replace, in conjuction with the Accuser DN, the abandoned BerÃ¢â‚¬â„¢taa hull. It does carry one of the new heavy photon tubes recently made available by Klingon scientists. It also is a four engined vessel, sporting two nacelles above and below the rear section of the ship. (Historian's note: This vessel may have been a direct predecessor to the Vor'cha-class attack cruisers of seventy-plus years in the future).
Length: 412 meters
Mass: 670,000 metric tonnes
Maximum Impulse: 1,230 kellicams per second
Hull Rating: 3.7
Shield Rating: 57.5
Maneuverability Rating: .33/.19
Forward: 4 disruptors, 1 heavy photon, 2 particle cannons
Aft: 3 disruptors, 2 particle cannons
Port/Starboard: 3 disruptors each
Tactical Discussion: These ships are powerful, with decent shields and weapons, but average hull strength. They pack greater firepower than the equivalent Federation battlecruiser, the Excelsior, but give up shield and maximum speed advantages for this greater firepower. They are extremely competent ships, and rare enough that command of one is only granted to the best commanders in the Klingon fleet. They tend to be sector flagships when a dreadnought is not available, which is often. Currently, there are about two dozen hulls in service, with another six under construction at any given time. Build time is considerably less than the larger hulls in the fleet, as this ship is built on a lengthened and strengthened D7 platform. However, the ships share few components, so build time is well over two years from the laying of the keel until trials.
(oh my whoever made that model you showed there was probably blind and asleep)

*edit* here are some additional pics for the D5 that might prove useful:
**second edit** that loophole part refers to the fact that the D5 reference for the TOS era comes from the fact that an old almost senile Klingon warior called his ship (the Klothos) a D5, although the Klothos doesn't look anything like a D5
