FRANK. B. ELDREDGE. MANSFIELD
OCT. 10. 98.
Frank B. Eldredge was in the insurance business but was also an active philatelist, helping to explain the artful manuscript cancel above.
From Mekeels Weekly Stamp News, Jan 11, 1913:
In 2014, the stamp immediately below was posted to this site. Frank Sente's unusual copy of a Scott R162 with what appears to be both horizontal and vertical printing by a firm or individual with the initials C. E. C. has remained a mystery. We speculated that its origins might come from the Charles E. Cornell company, which had a similar appearing initial and date cancel, that was otherwise known only on proprietary battleships, though that association has always seemed a bit dubious.
A few days ago I was examining stamps in my possession and found a second R162 with identical markings.
