Pelengas are still selling spearguns and here is a description of the "Magnum Profi" model which is distinguished by that longer plastic screw fitting on the nose which was commented on here some time back.

Here is what the company say about it:
"The Pelengas Magnum Pro 90 shotgun is an updated Pelengas Magnum 90 shotgun with some changes and a very rich kit. With this kit, the shotgun is already out of the box, essentially ready to hunt.
The model is designed based on the analysis of more feedback and wishes of spearfishers from the most remote corners of the country who use TM Pelengas equipment without the possibility of routine maintenance in the service center. The following changes were made to the design and equipment.
1. To increase the autonomy of the hunter completely changed muffler. Now the vacuum cuff can be changed when needed without removing the three-fingered winter gloves.
2. An inner centering ring was added which prevents the cuff from being scuffed by the harpoon shank when loading.
A centering cone was added to the aluminum part of the muzzle to improve the tightness of the vacuum collar.
4. In the back part of the muffler there are slits for a wrench, for possible self-disassembly after a long period of operation (which implies the probability of sticking of the sealed parts and mechanisms). Key included.
5. The top of the receiver has a light (contrast) coating to improve sighting qualities.
6. There is a spare vacuum collar in the back plug that covers the threads and stash valve."
