I had previously half way cleaned up the Dragoon lock casting set I had purchased several years ago from Blackley & Son in the UK. At the time they were moving their facility and foundry and did not have the screw set for this lock. After several unsuccessful attempts to have a set delivered I gave up and am now making all of the required screws. The bulk of them will be 6-40 although I may use an 8-40 for the frizzen pivot screw. I have machined the tumbler and done more clean up and polishing on all the parts. The cock is fitted to the tumbler shaft. I will do all the internal fitting with some temporary 6-40 machine screws but will then machine the correct length and shouldered screws to replace them.
Correction, blackly and son was not moving…. They were running away ! That guy owes me a few hundred in parts since 2017.
