The snap-on/-off forearms either the Fox & Kremer or the F.T. Russell Patents seem to have remained in use through at least the first 600 20-gauges and at least the first 500 16-gauges, well into the Gough style engraving on the A-/AE- and B-/BE-Grades. I have recorded a couple of very early 20-gauges with Deeley lever forearms. I too have pictures of CE-, XE- and DE-grade escutcheons in smallbore forearms, but don't have an AE- or BE-Grade either early or Gough style.
