Sometimes these folks can assist
http://www.wisnersinc.com/additional_info/Mirokusprings.htmlPart of this article says
"FINAL COUNT DOWN - After Chas Daly discontinued these Miroku guns in 1976 or thereabouts, Browning stepped in & had Miroku make guns for them. This basically the same O/U was then known as the Browning Citori model. During manufacturing under Browning's name, the types were also changed as things got improved. The type 4 Chas Daly gun appears to be basically is a Browning Citori pre-type I, which had coil mainsprings & top lever spring. However parts for the Citori type I, are now obsolete, but Western Gun Parts in Edmonton Canada purchased the last remaining parts from Browning a few years ago, & does have some parts left in inventory. Bear in mind however they may not be an exact interchange with the all the Charles Daly guns."
