I notice no one has answered your query. Probably, and sadly, because the badges are so hard to find, especially the pre-'47 versions. I once had a few of the Scout unit badges but they went to Arctic Medals in Calgary, Canada and he moved them on. He does, however, stock IA badges, so the site is worth checking periodically.
No idea who might have them in the UK/EU. And buying out of India/Pakistan can be dicy because the quality is so variable and too often just plain bad.
Good luck with your hunt.
