help identify hunter box hinged gold case please....

I have a very nice box hinged heavy 6 size hunter pocket watch..i can't find any reference to this maker mark in the complete guide to watches or any place else I have looked.the only marks on the inner cover is a serial number and a small hallmark of a mans head profile looking to the left..no names or any other marks on the case..heavy box hinged case and I am suspecting it is solid gold..is there anyone out there that knows what the brand and gold content may be? thanks in advance..Vic

Does it look like this guy?

A picture ??

regards,
bb

best I can get

case is actually a size 8

30yr GF - I believe (There is a picture of this stamp in the PG)

The few I have run across have a very heavy layer of gold

I finally seen the little picture in the price guide.it could be the mark,but not positive..thanks for the info...
