I have a Precision 10-40 with roll chart that covers nearly all of the octal, loctal and miniature tube types, but I was wondering if there is a supplemental data book or booklet that has settings for older pre-octal receiving types and for transmitting types that are commonly found in vintage and amateur boatanchor gear...Any references or sources is appreciated.
