This lot is a Trix Whistling Signal Box Article No 276 in OO scale. The signal box is in good condition, though I have been unable to get the whistle mechanism to work. I believe that it is all there - the internals are shown on one of the photographs - however one wire needs a resolder. I suspect a little bit of tweeking on a screw or something may be required to get the whistle to work - or maybe even a replacement bit of electronics. What a great idea though for a trrain whistle to sound from the signal box just as the train was passing  - vintage 1950's item so no DCC sound available then! Item comes complete with box and all inserts plus instruction manual and spare Euston signal box name.

Please ask any questions that you may have and I will try to help you
