Finkle, you find it probable because you wish it to be so, not on any evidence. The cross and crown feature on Zion's Watch Tower's later issues was a common and commercially produced type fixture [matrix], used on 'Christian' publications.
Here is what Schulz and I say in Separate Identity, volume 1:
Symbolisms
Decorative motifs found on Watch Tower publications are interpreted as Masonic. From an
early date a cross and crown design appeared on Zion’s Watch Tower’s front
cover. Because it was also used on Masonic paraphernalia, notably on the ceremonial
swords, the presumption is that Russell borrowed from Masonic forms, covertly
announcing to all “in the know” his Masonic connections. The logic flaws behind
this reasoning are astounding.
Cross and Crown
Masonic use of the cross and crown
symbolism derives from Christian usage. The symbolism became popular in the 17th
Century at least in Christian phraseology. In 1621, Francis Quarles wrote the
poem Hadassa: The History of Queene Ester. It contains this couplet:
The way to bliss lies
not on beds of down,
And he that has no cross deserves no crown.
There is a high probability that
William Penn took the title of his famous essay No Cross, No Crown from
Quarles’ poem. From Penn and others who wrote similarly, the cross and crown
coupling became popular. For instance, Matthew Henry observed in his Exposition of the Old and
New Testaments (published in several volumes between 1708 and 1710): “We only bear the
cross for a while, but we shall wear the crown to eternity.”
By mid-19th Century the phrase, “we
must all bear the cross before we can wear the crown” had become common,
finding its way into poems, homelies, sermons and common speech. Russell would
have heard it repeated ad nausium. The cross and crown was found as an
embroidery pattern; it found a place on Sunday school pins, on convention
ribbons, and on jewelry, and this long before it appeared on the Watch Tower’s
front cover or on a Masonic sword. The cross and crown symbol found on The
Watch Tower in the early 1890s is a combination of type matrixes commonly found
in a printers type drawer. The revised version from the later 1890s is a single
type face, also common in usage.
