Here is quick review and comparison of three helmets:
1. Protech Delta LT 875
2. Rabintex Attack
3. Rabintex Attack ACH-1
Why here is Protech Delta LT 875? Because Protech was a distributer of Rabintex in early 2000`s.

The main helmet is Rabintex Attack of course. Yes this is original very rare piece of gear. Other helmets in this review because they looks like origanl with some differences. I have made several pics where all this differences presented. Attack and Delta helmets are M size, Attack ACH-1 - L size. ACH-1 have same screws with othe helmets but they have been replaced to mich type because chinstrap have been changed top ops-core one. In same time chin strap of Delta helmet have been changed to original Rabintex stuff. ACH-1 Have predrilled three holes. Delta have one hole at the back where old chin strap was fixed with extra screw.
Overall view:
All helmets have equal dome shape. Same surface roughness. Same thikness of shell.
Delta`s back hole fixed with green stuff and painted at other side. The tags are missed
Rbh Attack Tag
RBH Attack ACH-1 Tag
The main difference in nape cut. This cut is a visit card of this helmet. Delta have almost same cut with Attack. Attack ACH-1 have cut looks like mich type of helmet have.
Then differences going with ear protection part of helmet. With the shape of it. Attack helmet have little bit smooth transormation from side to back then a Delta
As for Attack ACH-1 it goes like a mich type shape
Here I placed Attack and Delta to each other an drew a red line to see shapes better
So as result we have two helmets that looks pretty similar to Rabintex Attack. Delta helmet almost copy of Rabintex Attack. Attack ACH-1 less. But if you carve back cut of ACH-1 to several centimetres it will have better look.
This helmets is real to get at ebay and in shops. Really. I bought three Delta helmets. One at
https://www.modarmory.com/ and other at auction. ACH-1 at ebay. Delta was bought for 100-180USD. ACH-1 for 180USD.
Good luck at CSOR or SASR renaction
