Hi Widzrw,
Sorry, I realised the second I hit submit that I'd referenced the wrong Whiting Company. The mark I believe, belongs to FM Whiting.
You can find out more here:

As far as the pattern goes, it's obviously can't be Lily as that is a pattern belonging to Whiting Manufacturing Co. You will see patterns from FM Whiting on the above link and you may recognise yours there.
Cheers,
Steve
