OK I have figured out how to answer my question. The color matches the stamp illustrated on the
Canada Post Archives printed on July 1, 1859. It shows a perforation of 12. The Unitrade Catalogue says that the 16i must be perf. 11 3/4 on all edges and the 17b perf. 11 3/4, 12 x 11 3/4. Therefore if this is a 16i the perf. on my picture below must be 11 3/4. I think I need to buy a perf. gauge as I can't tell if this is 11 3/4 or 12 perf. using a ruler.
