another idle curiosity question, gentlemen.....the dickson action body in the drawer full of exotic goodies has two small diameter holes just below the flats, and maybe an inch apart - what function do those holes/pins provide?

i have stumbled upon another scottish gun photo....a bothwell gun with holes that appear similar, https://www.doublegunshop.com/forums/ubbthreads.php?ubb=showflat&Number=549131#Post549131

have never seen (or perhaps noticed) whose penetrations before now....is this a scottish peculiarity?

best regards,
tom
