Mercury Glass Bells 1960s (Smaller UK version)

I picked this one up in 2021 for 25p in a charity shop, and it clearly dates back to the 1960s, or possibly the 1950s. It is the same as the 'Classic' bell but in a smaller scale, 5cms high excluding the hanging ring, with a diameter of 4cms. And it has a working metal chime just like the larger counterpart.
