Reproduction WWII German Enigma Machine Tab for Button Long

For sale is a reproduction tab for the button long; it is not listed in the blueprints.  These tabs screwed into the bottom hole of the button long/key stem, and depressed the leaves of the leaf switches when the button long was depressed on the keyboard.  They are being sold individually. This tab is made of Cr12 steel, and comes with an M3 metric screw.  Normally the tab is screwed into the bottom hole opposite the cutout for the anti-twist device.  Occasionally the hole threads don’t want to accept the threads of the tab.  If you take the M3 screw and screw it completely through the hole from the cutout side and then back it out all the way, you will find you can now screw the tab into the hole from the opposite side with your fingers.  The button long occupies the top tier of the keyboard, and that tier uses nine (9) button longs.  The Enigma Museum webpage for The Restoration of Enigma A16878 has an excellent picture [picture #81] of the tab in use.  Original tabs had a slot in the top for a screwdriver:  mine do not because you can use your fingers.
