Hi mate,

Mr Hiller's excellent book has quite a bit of info about these...not sure if "Millita" was a brand of either Martin Pulverman (importer) or Friedrich Langenham (maker)...designed for shooting clubs, army cadets, etc, where you can assume they would be racked and a simple tether placed through the eyelet in the barrel release lever?...There were samll, medium and large models, and different types of barrel release too, and they seem to come in .177 and .25 cal smoothbore...
