Clyde Blowers chairman McColl, former Blue Knight Paul Murray and ex-club chairman Malcom Murray staged a two-and-a-half-hour meeting with supporter representatives at McColl's East Kilbride HQ.
None of three men spoke after leaving the building, although it's understood the discussions went well as they answered queries posed by the Rangers Supporters Trust, Rangers Supporters Assembly and Rangers Supporters Association.
Meanwhile, it is also understood that former oldco director Dave King will fly into Scotland on Friday for talks over the coming days with both McColl and the two Murrays, as well as the current board.
McColl and Paul Murray have been battling boardroom bosses at the club since August.
They successful applied for an interim interdict at the Court of Session last week, forcing the postponement of the club's annual general meeting, which should have taken place on Thursday.
The action was sparked when former chief executive Craig Mather blocked their bid to have a motion calling for the appointment of four new directors being added to the AGM's list of business.
In a fresh twist last Wednesday, Mather and fellow director Bryan Smart then resigned their posts, leaving just Stockbridge and James Easdale in charge of the club's board.
The club announced £14.4million losses for the 13-month period to the end of June amid allegations of failings in corporate governance, but Paul Murray and his partners have not given up hope of winning control of the boardroom when the club does finally stage the shareholder meeting, which must take place before December 31.
