Here we have a very cool 1987 REAL Jubilee Series 25/50 amp with a custom made GJ 2x12 cabinet made to match the head.
The Marshall Model 2553 is the compact "small-box" 50-watt head from the 25/50 Silver Jubilee series. While it shares the exact same internal circuitry as the full-sized 50-watt Model 2550, its narrower chassis was designed specifically to match Marshall's 2x12 mini-stack speaker cabinets.
