I had a discussion with Tracie as to why he had not written anything about the Maxim Silencer in his book, to which he replied: "I can only write about that which I have seen."  I decided to supply these photographs of a .45 Maxim.  It appears to be exactly the same as what's pictured in all of the Auto-Ordnance sales literature of the period.  This silencer was purchased from a gentleman who had it mounted on a .410 shotgun for use on shooting squirrels. Seems he didn't want to disturb the neighborhood.
