Excellent , sounds like your boss could be converted. One of our Germans did have a Shoei MP44 on the day , and very nice it was too !
Now for the Fake Bake. I painted all the plastic parts with Krylon Fusion colour #2340 espresso expresso (yes that's what it's called). Let the parts dry for about an hour. Next you'll need some Black acrylic paint, The water-based non-toxic type you can get at most crafts stores. Pour some paint onto a palette and thin with a little water. With a model brush start dabbing the watered down black paint onto the brown parts. This part is hard to explain but Bakelite has a brown-black mottled look. If you put on two much black you can easily thin it down with more water or scrub it back off again, Experiment until you are satisfied and let dry for an hour.
Next you need to clear coat over the black or it will rub back off again. I used Testors #1260 dull cote (available at most hobby and craft stores). You can use other brands (Krylon makes a flat clear cote but its hard to find). But some may not be compatible with the krylon and cause cracking or crazing (test before you spray your parts).

Hmmm , nice cat ! Any chance of any more pics ? The stock looks nice too !
Real steel longer HK33 mags should fit , they are slightly bigger than MP44 ones but most wouldn't notice the difference.
I still get asked if mine is an AK47 
I take it you got that 40rnd aluminium mag then and did the mod?
Hey do you want more photos of the gun or the cat 
As this HK is not for me I have got an other order in quick so I have one to mod later on after my 30 is done.
