Hi Scrimnet
Not having much luck finding the lodge in Wood Green
I have checked Grand Middlesex Banner 1930
Grand lodge of England 1940
No lodges in Wood Green
I may be able to get a check on Grand Lodge England 1920 (after the weekend)
My guess he was in the Grand Executive Banner as they did have lodges in that part of town. The only problem is all their records were destroyed in a fire at Manor House years ago 
I do have a few names of brothers that were founder members of lodges (but not many)
For him to pawn his jewels (brothers still use that excuse when they forget to bring their jewels to a lodge
) My guess is they were Grand Exec because if he was high up he would have been a knight & the jewel is worth a few bob, they see on ebay for over hundred pound now! 
I will attach a picture of mine so you can see what I mean (its the large cross one)
I will keep digging for you!
What was his name?
Den
I'm really sorry if this sounds stupid, but I know nothing about the Buffs so I'm having a bit of trouble understanding all the posts.
The third medal in your picture (the big cross) - What was it called and what does it stand for?
I've been trying to identify the medals in this photo of my Great-Great Grandfather John "Jack" Hainsworth (1846-1912). The one in the centre looks very similar to your cross.
I don't really have anything else other than this photo. I know he was a weaver in North Brierly, Yorkshire from the censuses.
Do you happen to recognise the other two medals?
I really do appreciate any insight you can offer, as I'm a bit lost as to where I can start researching this.
