Yes the factory records still exist for most guns:


Per the fox collectors site:

Write to John T Callahan at 53 Old Quarry Road, Westfield, MA 01085. Provide the serial number, gauge, and grade and enclose a check for $30 for Sterlingworths and $40 for graded guns. You will receive a letter in 4-8 weeks.
