I always preselect crossed arrow marks as follows:
Crossed arrows with four feathers each over numbers/letters was used by "Home Interiors & Gifts" (HomCo); they mostly traded Asian imports (Japan, China, Taiwan, etc).
Two crossed arrows with three feathers each and more than two digits/letters is a mark used by Arnart Creations; they mostly imported from Japan.
Two crossed arrows with three feathers each but no more than one or two digits were used by the Kalk factory in Eisenberg/Thuringia.
If none of those fits, I grab a book and try for more
