    Wanted : British wooden or bakelite Detonator Rectifiers

    Good afternoon
    Does anyone have any spare wooden or bakelite Detonator Rectifiers tucked away that they would be prepared to part with please. Cash available, or prepared to swap if I have something that would make you happy. WW2 vintage preferred, but interested in whatever you have available. I attach a couple of pictures of examples, but I know there were other patterns.

    Thanks in advance.
    Cheers

    The description should be Rectifier Primer 1 oz GC. Originally to rectify the central detonator hole in the 1 oz guncotton primer.

    Thanks AE501 - Nice to know the correct description.
    Glevum - They were a tool used to enlarge the detonator hole in various primers such as the 1 oz guncotton primer mentioned by AE501, allowing the insertion of the detonator. Presumably this was to prevent the detonator itself being used as a "tool" with obvious unpleasant consequences. Not quite sure of the dimensional differences between the existing detonator hole and the detonator itself, but I am sure that someone will know.

    Detonators No 27 Plain and No 33 Electric were both 0.26" external diameter.
    GC primers often had a little lip of the glazed outer cover over the hole entrance. The tool was used to flatten these to allow detonator free access. The finishing process of the primers was quite crude and the variation in hole diameter was quite marked. Sometimes they were so bad that they could not be used and were destroyed.
    The outer cover was glazed nitrocellulose which was applied wet moulded to the fibrous dusty dry GC inside.
    Primers 1 oz CE were far better made and easier to produce. They were wax coated and solid.
