I saw this on Ebay made an offer and the seller took it. I've used one of these for decades they work great!
This is the 1st one I've seen for sale in years. Trident makes a cheap looking version of this type of buckle but this is the original high quality buckle.

That's a very interesting design!

Very nice. I suggest a little Muriatic acid (Don't inhale.) scrub, Baking soda. (Nuetralizer.) Warm water rinse. Sorry, maybe to "Old Skuule."
Vinegar will work just fine.
Really cool..... Definitely, dive with it.
Cheers.

I think phosphoric acid is the proscribed treatment to passivate stainless. You can buy it as naval jelly.

I agree.....The comment was made only for his amusement, because of his age, and vast diving experience.

The buckle arrived today. I was going to put it on my dry suit weight belt for a spare and to eliminate changing the buckle from one belt to another, it's not hard but, forgetting to do it can be an issue come splash time! But then I thought if I do that it'll hardly be used at all So I decided to instead put it on my B/P harness belt where it'll get plenty of use!

The rust wiped right off with a little WD-40.

Muriatic acid is concentrated hydrochloride acid, and can be pretty dangerous, not only to inhale but also on skin and eyes. I wouldn't recommend it for cleaning of lightly rusted stainless steel, which this buckle is made of.

Use an ultra sonic cleaner.

Actually, muriatic is diluted hydrochloric. Usually about 30% of pure hydrochloric.
