I just obtained this beautiful Griffin and Howe Sporter. I said it is mine for a while because, like the land we own we are merely caretakers of these wonderful things, until it is time for someone else to care for them. It is a 30/06 serial number 1512. I am told it appears at pages 181 and 182 in S.R. TRUESDELL'S BOOK THE RIFLE, ITS' DEVELOPMENT FOR BIG GAME HUNTING. P.S. I did not buy it from Champlains on Guns International.
