The retaining collar is just a short tube so no bother. It often drops off when removing the stock! If that is the problem, I will measure one and draw up diagram a replacement! I got fed up with these dropping off and designed a new replacement for the retaining screw assembly which includes an integral collar. Have since thought up an easier solution but haven't tried it yet!
I had contemplated adding a stop to the trigger housing since that is where the problem lies!
These are the little things which make life with out-of-production models so interesting! No different from vintage cars etc!
Oh by the way, I have 5 BrumBows in various guises and two special Tomahawks (a V-Mach Cobra and a Venom Sidewinder) so potentially many special bits and pieces!
Happy airgunning!
