Good ole Radomski at his comfy Toronto address flogged made in Canada "Ardex" products', that featured leaning maple leaf logos identical to those of an Austrian (H.G.W.) maker. But, he did also openly market and import the Iltis line, probably knowing they were too good to be re-branded. "Made in Toronto" never did have much cachet, nor fooled knowledgeable trades people. Good spotting and you're correct. By convention stamps are generally (95% of the time) on the left (port as opposed to starboard) side of the head and the two Iltis heads I have are like that. Some heads are symmetrical (same sweep of the blade at the toe and at the heel) and if your's is one of these just leave it be. If the eye is tapered for wedging purposes you may inevitably run into some problems but if not who cares.
