Hi Johnnyfl,
see post #99
Unlimited Run - My version of the "Masonic Brick" from National Treasure - foam and acrylic version for the cast of acrylic brick, directly out of the mold.
The grey one you have mentioned are from the initial run. I have managed to get a better result out of the mold here (different pigments added)
I have some material for one more cast to make for you + still have some finished / colored ones (without the plaster - white finish - added).
Let me know if you are interested. Of course I would cast one for you
