Name:   J W Smith
Regiment or Corps:   The King's (Liverpool) Regiment
Regimental Number:   241214

Ancestry also have a MM record for J W Smith (241214).

Looks like there's a Pension Ledger card record for a Vernon J. Smith (15357).
And another one for a Joseph Vernon Smith (P/15357).

Also, a record for J V Smith (3228) in the UK, World War I Service Medal and Award Rolls, 1914-1920 set.

Not sure if the above are one or two men. Possibly some typos with the forename initials on the various records?

In which case, it's always a good idea to search with just surname + service number(s). So many military records have just the man's initials + surname. So drop the first name(s) when searching for military records.
