If the image of the watermark you are showing is the one from the stamp you have when viewed from the back side of the stamp, then you have HU 25IB/B2, one of the minor variants.

But all the 4 stamps I mention are with the same watermark and RevSR.

@Effie can you check this, is there another watermark variant for this issue??

@Theopimus As You got a very good idea from @DJCMH, pls check this link.

First of all check the perforation, is it line 11,5 or line 13 x 11,5, according to the image, I guess this is line 11,5

Should be this one...

Does not mean anything that all 4 stamps have the same watermark, it means all of them are this stamp

The Watermark must be checked from the front by HUN philately, but to be able to compare with major global system the back images are placed here on colnect since you check the watermark from backside.

This is Michel HU 25A main stamp and according to the WM position on of the 3 subvariants must be picked up.
