Funny you say that. After finding my second Mondiane, it made me want to know about more of their aquatic named models but info on this era/line of the brand seems to be nil.
Nice! I watched a black Herring (exaclty like my silver one) go on eBay a few weeks ago for far more than I was willing to pay. Seems some people appreciate these.
Latest ebay pick up. Basket case for a cool fifty. Cleaned up nice. Love the diving tank logo. Never seen one before. Surprisingly Tri State signed movement and case.
