How,
.....pages 44 and 45 of Old Frank De Haas's " Mr Single Shot's
Gunsmithing Idea Book" ISBN 0-8306-0111-2.........
those pages comprise a "Centerfold" ,....full scale RB action cutaway drawing, with LOTS of alphabetically coded detail notes below. Pages 43 to 48 are comprised of a full round up on the thing,....in his inimicable, clear text.
........according to De Haas, " Freund obtained a patent on this conversion ( #160,762),......" goes on to say " The patent drawings do not show all the details of it's construction, but let me assure you that Freund's conversion is not easy to duplicate."
I reckon the large drawing I have in front of me is the DeHaas
Version,........like a lot of his designs, it's VERY "Busy".
I'd advise sacrificing a RB action into a "cutaway" fixture, before attempting this little stunt.
That book can be hard to find, lemme know if you need photocopies.
