Made by ACME, England, of.... what looks to be Bakelite, it is 14 1/2" in length. I've been advised that prior to mobile phones etc when the work gangs were working on the rails a 'Ganger' look-out was used up and down the lines to blow the horn to warn the gang of approaching train. In good overall condition and makes a heck of a noise!
