These two rounds came from an old collection in a little envelope marked "38 Extra Long Frank Wesson Rifle" and "Very Rare" in pencil.  The two rounds are different with one having a folded head and flat copper primer, the other has a formed case head and a large domed copper primer.  First round measures: .439-rim, .375 base, .377-mouth, .349-bullet, 1.617-case, 2.096-oal. Second measures: .436-rim, .378-base, .375-mouth, .360-bullet, 1.598-case, 2.111-oal.  These are interesting old rounds, I think the first is a Wesson round and the second is the similar Ballard round.  Free shipping.
