28mm Wallace and Gromit?

I'm still painting the 3D printed model of the rocket from A Grand Day Out I got a couple of weeks ago, and it occurs to me that while I've got it for my Martian adventure, for which I'll be using (clone of) Lego minifig astronauts, it's actually closer to 28mm or similar scale, as used for a lot of wargame and RPG figures. I'm not actually over-concerned about scale, I just want it to be a fun model to amuse the players, but I suspect that at some point in the future I may want to run another Wallace and Gromit adventure now I've got the thing.

There's some fanfic based on the last adventure I ran with them here: https://tthf.me/BlD3

What I'd really like to get, if not incredibly expensive, is some appropriate 28mm figures - Wallace, Gromit, and possibly the criminal mastermind penguin, Shaun the sheep, etc. I've got a vague idea that I've seen something of the sort on sale a good few years ago, probably in someone's range of "very like something from film and TV but we can't say so" figures. Does this ring a bell with anyone?
