In most cases, you will never find the font you are looking for, trust me. A unique logo such as this will almost always have a handmade typeface by the designer, or one that is bought for a high price from some good font foundries. If you can find whatever this is, good hunting
Seems like a pretty easy set of characters to make yourself imo, or to find something similar.
I gave up in the end and made it. I was looking for the font though to make the letter's more accurate as I know some of the corners are sharp others are round but being so small you can't tell. Will have to take a picture next time I am passing the shop
