Lot of four (4) vintage heating and soldering torch heads that look to be in good condition.  These were likely used with blacksmithing and/or plumbing in years past.  Each has a wood handle painted green and all had the name "Insto-gas" printed on the handle.  Some of the names are worn off some.  First, is a brass soldering tip torch head that measures about 14" in length.  Second, is a rare double head heating torch head, which was likely used for heating pipe or similar.  Third, is a heating tip that has a cast iron head over a brass tip.  The cast piece is marked with 1G and No, 3.  Last, is a heating "rose-bud" type heating torch tip.  The tip has been brazed at some point in time.  All torch heads have a shut-off valve, and each is genuine Insto-gas and marked as no. 01.  These were used likely with propane gas?  Please study the multiple pictures for additional details.  These are each very hard to find.
