Section F.
ARTICLES CARRIED BY A STUDENT

This section could very well be a section in itself as even the many articles mentioned in the following pages do not in any way cover the whole field of material which comes under this heading.

Almost anything which a person carries or makes use of professionally, by way of trade, for personal convenience or toilet purposes, can be adapted for concealment.

This section covers all types of articles but by no means all varieties, and for simplicity it has been divided into sub-sections.

No. 1 sub-section deals with those concealments which are possible in the actual personal clothing and contents of the pockets of the average man.

PERSONAL ARTICLES

The following is a short list of some of the articles - which have been adapted:

  • Collar stud
  • Collar stiffener
  • Coat button
  • Cigarette holder
  • Door key
  • Fountain pen
  • Finger ring
  • Pocket petrol lighter
  • Pocket torches
  • Pen knife
  • Pipe
  • Pencils
  • Shoe trees
  • Shoulder paddings
  • Shoe heels and soles
  • Spectacles

The following examples show what can be done with these articles:-

Collar Stud.

A metal collar stud with a celluloid back can be used for concealing micro prints. The celluloid back is removed, and the print placed in the cavity. The celluloid is replaced and secured with a small application of Seccotine [a brand of glue].

Necktie.

A necktie can conceal a small code printed on silk. The code is secured to the back of the tie with two small press studs. This method is used in order that the code may be very speedily used and replaced. A tie adapted in this manner is worn quite normally without any bulkiness showing.

Door Key.

A door key has been successfully adapted for the concealment of small microprints. The shaft of the key is drilled to about three quarters of its length, and a small stud is made which fits into the hollowed shaft by means of a left handed thread. See illustration.
