Judge Dredd Lawgiver

I've been working on the Mk1 Lawgiver from the Judge Dredd 2000AD comics.

There seems to be 2 versions of the lawgiver, one with 2 ammo mags and one with a single mag, it seems that the artist's had quite a bit of freedom on the projects, so there was not a spercific Mk1.

So i have desinated the single mag as Mk1 and dule mag as Mk1.2
