I was born in 1944 and I don't think girls had hairstyle like Trixie's in the late 50s/early 60s.
I must admit I was looking at Trixie's hair and thinking nice as it is I didn't think it was quite right for the time. My mum was born in 1945 and I've seen lots of photos of her in the sixties with her hair back-combed to make it fuller. I remember her wearing rollers as well.

In his job it would be easy caught and his finger could be damaged.
This happened to my dad so he never had a wedding ring when I was a child, just a scar where he was very lucky not to lose his finger. He'd just been helping to load a van up in the loading bay at work and banged on the doors at the back to let the driver know he could go, and his wedding ring got caught and twisted round and went into his finger. Had to be cut off (the ring not the finger!).
