An old friend just handed me some old woodenware machinery and particularly a box joint jig with which I am throughly 'tickled'. I want to use it and can figure it out, but would like to find out more about it. It is/was made by the Carl E. Johnson Company of Lincoln Park, Michigan. I find nothing on the web about this company. It has a serial # but no model number or year of manufacture, so I assume there was only one model made. If anyone has information on this little bit of beekeeping history I would love to have it. Thank you, Edward Markus Heart's Home Farm
