Acme sell their products on their website as well.Lol, makes me laugh. Go to any decent shooting shop or gundog equipment supplier like Turner Richards and they will flog you a genuine Acme Thundered for a fiver or so. Oh sorry, they haven't been engraved with a fake logo have they
Also, if nickel plated whistles were that dangerous the UK countryside would be littered with a mass dead gundog handlers, picker - ups, beaters and sportsmen as they have been used for that purpose for decades including by me too. There's nothing like a Thunderer to get the attention of a hot Springer Spaniel who has gone off on one working up a hedgerow or game cover].
