Trying to match CertainTeed Hallmark pewter gray shingles

Reroofed house with these "shangles" a couple of years ago. Have built new garage & learned that they've been discontinued. Can't find a close match. Does anyone know where I could find them - I need 20 squares. Thanks.>>>

All-told I haven't done many Hallmark (originally a Certainteed product) jobs, but I have installed them every now and then since they first came out and they haven't caused me any remarkable problems. Maybe a different manufacturing zone is responsible for that. A few years ago I needed to match some HM30's which is what I was informed they were then being called, and ended up having to import them from a yard several states away in Idaho. All they were was a Glasstex 3-tab with extra strips glued on. I admit the rivulet granule pattern in the field is not duplicable but a 3-tab with strips added would be passable at a distance if you were in a severe pinch at least for general hue and texture.>>>

It includes an addition to the house(no motor coach). I'm in Indianapolis.>>>

I found several places a while back, that specialized in carrying discontinued shingles, but it will take quite some digging to find the,

One place was out of Littleton Colorado, if memory serves me right.

But, I wouldn't trust buying shingles that have been stacked up in somebody's storage yard for several years, especially if left in the sun.
