Thanks for your reply Pat.
Thats the site I had looked at but couldnt find anything - he had a very common name -Smith - and also if he lied about his date of birth its difficult to know which is him although it gives DOB on the site. Would have thought he may have given the correct day and month but not year but nothing tallies with thst either! Have a portrait of him in uniform but no nunber showing unfortunately. Thats why I wondered if there may be some records kept in the Isle of Man of the men who enlisted to try another avenue of searching for his records.
