@EggMan,
My best guess it that these fenders are from Aber for the E-50/75 tank. These fenders could easily be adopted for use on the first three prototype Tiger II's (V1,V2 and V3). Here is a link for these
Aber fenders. Click on the 'Download PDF instruction' link on that page to see what's included in the photo-etch set. I have a copy of these fenders and the front fenders are the same as for the prototype.
I had scratch built a set of the front fenders for the prototype Tiger II I was working on (still unfinished) some years back before this set became available.
Hope this helps,
