Just fitted my first pair of these and they are the mutts nutz. I couldn't find them listed (being a dinosaur) but no doubt they are here somewhere

I've also just fitted a pair of these Protek screws to my 1927 light model. They offer 3 different finishes, to best suit the gun there being fitted to. They fit and look great. In the early BSA spares section on their website. John
