Anyone help identify these parts?

As per title, looking at making these out of 1/2" pipe for a local charity to raffle off but could do with a list of fittings (mainly the one that clamps to the bottle) if anyone could lend a hand?

I think the bottle clip / mech is just wedged in there

It’s a cam lock adapter

1/2” lever valve

1/2” blanked nipple / closed end

All the materials are going to be stainless

Materials cost around £50-80 ish

For the bottle clamp try quick release fluid connections.
