Small signal cannons were generally made
in the style of the period of when they were made.
  They were used
on ship and on shore to make salutes, to warn of danger, and to attract attention in the case of an emergency. They were also
used to start yacht races. 

Presented is an late 19th
or early 20th Century ship’s signal cannon with bronze barrel mounted on a wood carriage. It comes from Ireland where it was
discovered near Dublin, among a foundry’s scarp in 1959. There is an old type written label on the bottom which says it was
unlawful to possess such a weapon during the time of the “Troubles“, 1916-1921.
Its proportions are typical of a British warship’s long gun, and it is fitted to its original shipboard carriage. This
represents a fine example of a bronze  ships signal cannon with excellently detail and the correct

appropriate box wrench; a T-handled socket wrench was developed in the 16th century. Some screws used in
16th-century armour have slots (nicks) in which a screwdriver may have been used, although this tool is not shown. Deep notches
on the circumferences of the heads of other armour screws suggest that some type of pronged device was used to turn them.
Slotted, roundheaded screws were used in the 16th century, but few screw-and-nut-fastened clocks are in evidence earlier than
the 17th century. Metal screws were called machine, or machinery, screws since they were made of metal and mated with threaded

We estimate its age as at least 120 years, but
it could be earlier.

of its age, but is in overall fine condition. However, it is sold for display only. The trunnions are
