Thanks, Dave, that's quite a collection of boxes and information. The last shells John Olin shipped to Henry Bartholomew for the Bartholomew and Buckingham Becker Foxes were dated November of 1948, the month that Nash lost Bo Whoop. I assume that the 1 3/8 ounce Lubaloy shells that Tom Kidd posted pictures of on one of these sites recently were also November 1948 shells, because his came out of the same garage that mine came out of, the Bartholomew digs in Fort Washington. I'm not ready to open the sealed case yet, but maybe Tom Kidd would donate a few shells for a patterning experiment, maybe out of one of Nash's or Henry's Beckers. I was ready to open my case and spread the wealth until a poster on one of our gun sites trashed the provenance. I may do what previous owners of Buckingham-Bartholomew Lubaloy shells have done, shoot them at ducks.
