Well I've not been totally lazy and have been lucky eough to get my hands on some old plastic beaky marines and a couple of handfuls of metal marines. I've now enough for 2 tactical squads, a full devastator squad, and perhaps a full assault squad. I'm painting them up as Silver Skulls, partly as I'm relearning to use metalics (I'm turning away from NMM, it's just far too awkward), partly because they're a true RT chapter and lastly because you don't see them that often. Here's the start of them anyway:

Along with Inquisitor Thingy (need a good name for him)

And Captain Bob

Lastly I built this dreadnought/robot thingy a few years back and it's finally found it's place amongst the Silver Skulls:


Also a big thankyou to Mr Dee who gave me some helpful hints on painting metals that have made this dreadnought look sooooo much better than it did before.
