This is a slightly niche question, but I inherited a few vintage cameras from my grandfather this year - a kodak brownie, a soviet lubitel etc. - and I would like to carry them back home to the US from the UK (my birthplace).

There's lots online about traveling with more modern equipment, but does anyone know if I'm likely to encounter any problems going through security at Heathrow? Obviously I do not want to lose these cameras.

Thanks!
