It looks as though Beuchat airbrushed out the logos on the Jetfin copies, Mark, before inserting them into the publicity material. DRW Perhaps they had a Bolshevik working for them... ( Leon Trotsky and Lev Kamenev were removed from image! ) Eh Komrads?

I wonder if they could be Pearl or Kawasaki fins?

DRW, I knew I could get you to bite on that one! Did you see this film: I think I may have asked already but? I highly recommend it! Back to the conversation... The only Japanese dive gear companies are Kawasaki, Atomic and Seahorse: I'm sure there are others but! And what about Greek dive gear? JB

No, I haven't seen the film, JB, although I do admire Armando Iannucci's intelligent comedy when I listen to BBC radio. I'm just out of the habit of cinema-going at the moment.
Thanks for the names of those Japanese diving equipment companies. I am looking forward to doing a spot of googling with those as search terms.
As for Greek diving gear brands, Majorca sub, Glarosub and Balco sub are the three that come to mind. They make (or made) kit the way it used to be made before the silicone and tupperware revolution in manufacturing.

There may be one more Japanese manufacturer of a Jet Fin knockoff, but sanctioned, as it is Scubapro Japan: The Scubapro Japan Revo fin. You can see it on ScubaBoard's thread on the " Jet Fin XL vs Jet Fin Revo Grande." John

OK - it's been a couple of days so I thought it's time I'd added what I know about the missing fins 1, 3 and 4... Jetfin lookalike No. 1, I think, is the British "Concorde" Jet Fin: The ad above appeared in the British Sub-Aqua Club journal Triton at the outset of the 1970s. The fin was manufactured by or for Sous Marine Products: Sous Marine was founded by Collin Glass in the English Channel Island of Guernsey with a manufacturing base in the county of Dorset on the British mainland: And here is the fin again, minus the "e" in "Concorde", in the 1978 Sous Marine catalogue:
Stay tuned for Jetfin lookalikes No. 3 and No. 4.

Here's a front and back of some of those along with the HW Scubamaster, which like the Sportsways 707 and Dacor Turbo-II didn't come out until the 1970's: It looks like the engineers at HW really liked the USD Rocket Fin and their use of ribs JB

So I'm guessing my Atomic split-fins don't count as vintage?

So I'm guessing my Atomic split-fins don't count as vintage? Sadly, Peter McCarthy's original split fin patent only dates as far back as May 5, 1998, so well beyond the vintage era of diving equipment ending in the mid-1970s or so. And I think that the first licensee of the "Nature's Wing" patent was the Japanese manufacturer Apollo with its Bio-fins: DRW

And I think that the first licensee of the "Nature's Wing" patent was the Japanese manufacturer Apollo with its Bio-fins: DRW Yeah, I knew that. Just trying to stir the pot. Actually, my Atomic Aquatic split-fins were both lost on a night lobster dive in churning roiling seas. One strap caught on something and as I yanked my leg forward the fin came completely off. When I turning around to look (swimming in circles was actually very easy with just one fin) the other fin got wedged in a crack in the rocks and the strap broke when I pulled by other leg. After a fin-less ascent I bought a pair of the Apollo Bio-fins you mention. They are actually really great fins. You have to kick more times to go the same distance as with other (non-split) fins but the effort to kick with the split-fins is really easy. Each to their own. Not looking for a debate split vs. non-split.

...Just trying to stir the pot... I'm glad someone is-geeze! I was in Oakland last week and I saw a pair of Dacor Turbo-III's, "Huh, well I'll be!" I didn't get themas I have way too much gear that I don't use as it is. I at first thought they were Jet's, but they wasn't them: it was nice to see that familiar Dacor oval though! Jaybird

Scubalawyer- Hang on to those bio fins. Years from now somebody may change what we refer to as vintage. More than half of my equipment was "state of the art" when I bought it. Now its vintage and according to many LDS's unsafe. Go figure
