Hayford (International) spheroid and UTM?

Dear All,


I received an old dataset from the British UK Overseas directorate which uses 'UTM projection (Zone 57N) and the Hayford (=International) spheroid.'


WGS 84 cannot be used for this data and 'International 1924' is a datum that is used with spheroid-based geographic coordinate systems.


Does anyone know which UTM option I can choose from the projected coordinate system list in ArcGIS? 


Thank you
