Hi everyone
Wonder if anybody knows if this belongs to a font, or whether it has been custom desgined?

It's a variation on the famous & by Caslon, so it looks very familiar:

you can also check out Eva Black Designs ampersand post
and this dribble
or this ampersand blog
Came across Hera Big Black, which has an ampersand with the same thick & thin flavor of your image.
