I have solved half of the problem myself with further research. The Royal Horticultural Society’s Encyclopedia of Conifers says in volume one that it is a synonym of Abies lasiocarpa ‘Logan Pass’. There is an error somewhere as the two do not look alike. Mine is conical and L. P. is a little bun. Another source says that my conifer is also known as A. l. ‘Glacier BLUE’. What remains is how this error happened in the first place.
