Do you mean an actual working Franco-Crosti boiler or just an external resemblance of one ?

Ten of the BR Standard Class 9F locomotives, Nos 92020-9, were built with Franco–Crosti boilers in 1955. Like the German 50.40 these were 2–10–0 tender locomotives with a single feedwater heater under the main boiler.^[1]

The standard funnel was retained, but was only used for lighting-up and was blanked when running. The final chimney was located on the right-hand (fireman's) side, just forward of the firebox. The Crosti preheaters provided less improvement than had been expected, and were a problem for maintenance, owing to acidic fluegases condensing in the feedwater heater and causing corrosion. All were converted back to a more standard form within a few years, the preheaters remaining in place, but blanked off
