I remember Mr. Dent had the finest personal collection of anyone I personally knew...
He owed and operated Dents Dept. Store in Hialeah, Florida (on a side note : my cousin ,now 71 ,worked for Mr Dent in his shoe dept. while in High school)
I met Mr Dent in the mid 70's and went to his home , his den was floor to ceiling in Guns from 18th & 19th Century.
I recall Burnside's & Sharps , every manufacturer of 58 Springfield Muskets during the CW.
I recall Colts, he even had a rare presentation Colt , I believe it belonged to a railroad tycoon of the era.
I don't recall a Henry though he had a number of old Winchesters.. Of course there was so much to see and drink in that evening..
I was in sensory overload....
He gave me a book I still have, Illustrated Catalog of Arms & Millitary Goods Schuylar , Hartley & Graham
Cal.# 368 was a Henry Rifle in Caliber 44/100 it states.
