Carrier armour manufacturer?

[Bob Phillips]

I would like to throw a little information out about SDA - GALT.
I grew up in Galt about 3 blocks from the SDA plant. My neighbor was a traveling saw salesman and saw hammerer.In addition to a wide variety of handsaws SDA made the large ( 4 foot diameter) sawblades used in commercial sawmills. These type of blades are not flat but slightly dished so that at high speed they straighten out and run true. A saw hammerer was a skilled craftsman who traveled to service saw blades across Canada, and hammer them to run true again.
My mk2 carrier also was clearly labelled SDA GALT. The company closed 25 years ago ( maybe longer than that) and today the site is occupied by the new
Dunfield theater. Next to it is the large antique mall ( worth a walk through !!) that used to be the old Babcock - Wilcox- Goldie McCullough foundary where they made all manner of farm equipment, milling machinery, vault doors and safes etc. Back when we had industry close to home...B.P.
