I haven't seriously recorded graded guns like I have Sterlingworths. I do have photocopies of most of the tally sheets Roe Clark used to tabulate the graded 20-gauges for McIntosh's book, bottom of page 145.
From these pages, I see there are no cards for 203241 through 203500 and a smaller gap 203011 to 203099. There are two cards in this smaller gap, 203016 (XE) and 203017 (HE).
Continuing on with some 12-gauge Sterlingworth observations, it appears Savage made different guns in different serial number blocks. All the guns I've observed from 132649 to 132927 are SP-framed guns. All the guns I've recorded in the 133xxx range are drawbolt frame guns. The only guns observed in the 134xxx range are the Fox-Sterlingworth Wildfowls from 134102 to 134130. John Callahan's search of the records for Frank Srebro's The Double Gun Journal article on the Wildfowls, Volume Twenty-Six, Issue 4, shows surviving cards in this block up to 134142. I've recorded no other guns in the 134xxx range. In the 135xxx range the guns I've recorded are all in the 1356xx and 1357xx range and four of those five are 28-inch barrel Fox-Sterlingworth Skeet & Upland Game Guns. Again guns in the 1379xx and 1380xx range are SP-frame guns. All the guns I've recorded in the 143xxx range are drawbolt frame guns. Then we jump to the 160xxx range and the guns I've recorded up to 160434 are 26-inch barrel Fox-Sterlingworth Skeet & Upland Game Guns. Then another batch in the 1607xx and low 1608xx range. The 161xxx range is a mix of regular frames, then SP-frames and ends with drawbolt frames.
