Anyone still using a Type B burgundy British Passport?

I'm the last of my friends and family to still be using an old style burgundy passport. I got it in 2019, so its a hybrid Brexit passport, because its still the EU colours, but doesn't have "European Union" written on it, and it even still mentions "her majesty" in it. 🤣

I still have until the start of 2029 with it, as I will then need to update to the British Blue, since we now need to have at least 6 months on one to be able to travel. 🙄
