Looks like it is gold plated. Take it to jewellery and ask for acid test

I ordered a DIN conversion for an MR42 - are there specific instructions I need to follow? I might need to order a yoke nut socket.

I ordered a DIN conversion for an MR42 - are there specific instructions I need to follow? I might need to order a yoke nut socket.

The official Mares tool to remove the yoke nut is part # 46106201, and is a modified 25mm open end wrench. The modification is that the opening is elongated so that the jaws of the wrench reach around the 1st stage yoke and fully interface with the retaining nut. You can make this yourself by grinding a 25mm wrench to deepen it. Or a very shallow 25mm socket should work but make sure that your 3/8-inch drive ratcjet extension will through the yoke fitting.

Here is how to install it:

Worked like a charm. Used a long 5mm hex bit from Harbor Freight to install it, applied some Loctite 243 to the DIN adapter threads - the last tech to touch it didn’t use it but I did. Torqued to spec, removed the second stages/LPI/SPG and transmitter and had my reg on a tank to blow out any verdigris or other flotsam.

I need to get some Bondhus SAE and metric hex bits for my scuba gear. Noticed the HF one did get a bit damaged.

Okay, back to life......

So the reg is clearly plated ( can it only be gold?) on chrome ( not brass!?)........

I still think it should be an aniversary edition, but from when, 1984 maybe (35 years Mares?), '89 (40 years Mares?)..........?

Obviously something for Mares Nerds........

I can find no mention of a run of gold-plated MR 12 III (or any other model) from Mares.

Maybe it was done by a hobbyist. Small scale gold electroplating isn't difficult.

Looks like gold!

Don't want to hijack this thread, but I think that here are some Mares specialists, who know more than me about 'Vintage' Mares Regs.
I found this ugly Mares reg months ago, together with another 'normal' Mares reg.
I didn't find time up to now to service it, but I was wondering, that if that is a Special Aniversary Edition ( and for me it looks like that), maybe somebody here could tell me from which year that might be.......

I'd sure like to know about this to ... interesting .. I "made" one of these from a US Divers First stage I left in "weak" muratic acid once ... came out that color ..chrome had been burned off from the acid ..lesson learned ..
