Yes, in both The Parker Story and in the Serialization & Identification books.

Parker Bros. did so many weird and wonderful things to satisfy a customer's desires it boggles the mind. Some years ago, Jack Puglisi had this HEAVY 12-gauge built on a 6-frame, normal for an 8-gauge --

Normally 10-gauge guns were on a 3-frame, but we know of at least one 10-gauge built on the 1-frame which was normally used for the light 12- and heavy 16-gauges. One year when Kevin and I were doing the PGCA booth at The Vintage Cup at Sandanona, we had 20-gauges on the 0-, 1-, and 2-frames on display.

Unfortunately, the frame size charts in those two publications do not include some of the more unusual gauge/frame size combinations. Examples of odd combinations are ..410 on the #00, 28 on the #000, 16 on the #3, 12 on the #6, 10 on the #6, 10 on the #1, 20 on the #2. There are obviously more oddballs out there, because I have seen all I mentioned, and I don't get out much.

Look over the "Technical Information" link on the parkerguns.org page.
