My wife's grandfather served in Germany WW2 as a Canadian paratrooper, and we found this aviation patch among the things he brought back. I did google lens searches and more, but can't find ANYTHING at all. It appears to be ink-stamped on wool, but we can't figure out what the abbreviations mean or what the patch represents. All we know is that it's old. Any information y'all have would be appreciated.
Thank you!IMG_0152[1].jpgIMG_0152[1].jpgIMG_0152[1].jpg
