Help working out bridle make please

[lrw0250]

I have just bought quite a nice little pony bridle second hand from our local horsey facebook page for a few quid. Its nothing fancy but it does have a logo button on it which is black with the letters D and I overlapping in gold. Just curious to see if anyone knows the make? Thanks!

Can you post a pic? Even if we can't tell the actual brand, there are a few pointers to identifying good quality English bridlework.
