Thunderbolt 1 to HDMI adapter

Hi,

I am looking for a suitable Thunderbolt 1 to HDMI adapter to connect my 2012 MacBook Pro to an external monitor.

As I would like original Apple adapters - mostly because the probability that they work is the highest, does anyone know if Apple ever made those, and can tell the model number?

Or is Thunderbolt2 backwards compatible then I would take an adapter with TB2 2 HDMI.

But same question here: Are there any existing and what is the model number?

Or what 3rd party solution can I use instead?

It is a question to older hardware but maybe there is still someone who has some advise?
