There are quite a few going at Popham. They are all advertised on a noticeaboard in the clubhouse, I'd suggest you'd be best driving or flying down and browsing the board over a coffee. I was last there at the weekend, I didn't see any Beagle Pups, but a couple of C150/152 shares, and similar - certainly there are at-least a dozen on the board there in the ballpark you're looking for.
To save a wasted journey, do note that the clubhouse is usually locked up at about 5pm.
