My Tesla Talisman 306u

I made a little video on scanning through the SW and MW bands on my 1950s Tesla Talisman 306u.
I love this little radio and its features, especially the dial once it's all warmed up.
I do have a sticky volume switch, which you'll see in the video. If anyone can suggest a cure for this I'd be most grateful.
I'm a bit scared of opening it up but I know there's a great community of radio restorers here, so perhaps you can give me some tips.
You'll also hear my rather squeaky voice at the start too 😄
