Luke Nash who owns SMK bought the name and good will of Milbro from the Receiver. Mildenhall has long gone. Milbro pellets are made by Lanes of York for them in new moulds as the old ones were auctioned off by the same Receiver.
What's wrong with sticking an old name on an import rather than seeing an old name consigned to the history books. As Chinese airguns go, SPA makes a reasonable product to wear the Milbro name.
If the likes of AA won't make a new break barrel because of costs, there isn't much chance of SMK investing in a new range.
As for Morris 1100's, they couldn't be any worse than what British Leyland turned out.
