I've had literally dozens of 046 saws, don't recall ever seeing a metal badge on one. I am guessing they have to be pretty rare. I have quite a few 046 top covers and a box of model badges as well, no metal 046 tags there either.
If I remember right, the 046 was introduced not too long before the model numbers shifted to MSxxx. I've not seen a metal tag 046 either.
