Still hunting old New Britain wrenches. The double groove style, combo box/open, in 3/8 and 13/16. Maybe any over one inch also? Also an mildly looking at combo box end, deep offset, in 3/8 x 7/16. A nd shallow offset wrenches. Was just gifted a double box end combo, 1-3/8 X 1-1/4 NDF 218. But the next size in that pattern I have is a 3/4 NDF 206, so a bunch still missing there. Getting serious with the earlier series with the single bar backbone, especially in the combo open and box styles. See what you have, Thanks to the folks here, this is getting out of ha----is going great!! Thank you
