This one is for Canadian Stamps specialists. No mention of USA equivalent.  |

Didn't realize there were digital perf gauges. That's pretty cool. Are they accurate? |

Ever since I was a kid, I've used a White Ace gauge that is essentially identical to the black Unitrade gauges pictured above, differing only in the branding and the country of manufacture (U.S.A. rather than China). |

 Looks like both U.S. and Canada Gauges have the following in common: 11-72 (wheel) 11-70 (bar) 12-67 (U.S. Rosback stroke) 12-66 (wheel) 12.5-63 (U.S. Rosback rotary) However, only 11-72, 11-70 and 12-66 are from the same kind of perforators. |

Quote: Big question... 1 - Which is the most accurate gauge to use. To twist the first question around a bit ... what is the most appropriate gauge to use for each era of Canadian stamps? Of course the gauge must be accurate itself, but the larger point being, when I have a problem to solve, I select the appropriate tool for the task. Do I select a regular screw driver or a phillips? Similarly, I would select different gauges for small queens vs 1930s definitives vs 21st century issues. I do not believe there is a one-gauge-fits all. And it is often better to use a stamp of known gauge instead. |

Quote: And it is often better to use a stamp of known gauge instead. Good point John for collectors out there..I have used another known perf to arrange perf tips to see if in fact there is a noticeable difference. This would support perforation readings with what ever gauge you decide to use. Robert |

As per Hillson (expert in SQ) I use the original SG yellow Instanta gauge for them (purchased on eBay).  |

Here is my mother's "Whit-perf" perforation gauge. Circa 1960-63 I think. The left hand piece is a plastic sleeve into which the right hand plastic piece slides. At right in the image are scans of the back of the sleeve and insert. I suppose the sleeve kept the thing from bending or getting dinged or dirty. Although I used it for years, I switched to a Sonic Labs US multigauge some time ago which I find quite easier to use as the perforation section is at least twice as wide as this one. But in the interest of assembling a virtual collection in the thread, here it is.  |
