Looking for this vintage speargun

[swgino]

Hello.
I'm trying to locate this vintage speargun. It is definitely pre-1980 as a point of reference. Probably mid seventies.

I'm really hoping someone here can point me in the right direction.


Techinsub Pulce 40 speargun

If anyone has one or more of these for sale, please email me at gino@columbus.rr.com
I feel like I'm looking for a needle in a haystack, so hopefully someone here can come through.

Thanks for taking a look.
Gino
