 Neil,
I have both of those types of goggles. The upper ones were bought from a govt surplus store many years ago and are folded over in a stought brown card box. A soldier's army number is written on the strap and is for someone serving in "Cavalry of the Line". According to Brian Davis's book, they are MT goggles.
The lower ones that I have, are fitted with yellow tinted lenses, the fur and cloth surround is a pale blue and I think they are probably early flying goggles. I have just done a quick Google search for goggles (!) and found that the lower ones are in fact an early RAF item, "Goggles,Flying, Type Mk2" and introduced in 1928. 
Take a look at this;
