Period
Presumably made before 1966.
Canada
Victoria Foundry established in Ottawa c. 1850 by N.S. Blasdell. In 1873-4, the business was expanded, and new buildings and equipment added. The 1900 fire which razed large areas of Ottawa destroyed the Foundry's property, but it was quickly re-built and re-equipped at a site on LeBreton Flats, where it operated until 1965. c. 1967 it merged with the foundry business of Thomas Lawson & Sons (est. in Ottawa c. 1885) and McMullen Perkins, a machine shop operation (active in Ottawa since 1912). The new company, Lawson-McMullen-Victoria Ltd. moved it's operations to Ottawa east. LMV is thought to have been active until c. 1972-73. (Ref. 1) In 1965 the National Capital Commission (NCC) expropriated the land in LeBreton Flats on which the Victoria Foundry (and it's soon-to-be partner T. Lawson & Sons) operated. Demolition of the foundry buildings began March 1, 1966 and were completed May 5th. Mr. Don MacKenzie collected archival material, patterns, and other items from the site during demolition, and made them available to CSTM.
Function
To produce mold of desired size and shape, to be used in casting. Specifically, this pattern used to produce a valve handle.
Technical
One of 2 identical patterns for casting handles or pulls, identified as being for use on a valve. Each handle has short, square post for insertion in receptacle. Hole in pattern allows for insertion of hook or threaded rod, used to remove pattern from sand without disturbing prepared impression.
