Rogers often used the same chassis in their three lines so a quick look at Mallory shows 6M531 (6R531,6D531) as having 5 tubes 6A7M,6K7M,6F6M,75M and 80. Whereas the schematic doesn't show a Victory model I believe this is the one for 6M531. Bottom of half of the page on the following link (Saturn, Orion,Meteor, Cornwall).

Might be good for comparison for tube lay out.Since Rogers had their own line of tubes and with the outbreak of WWII in 1939 some of the original tubes like 6A7M and 75M were probably substituted. Here's a chart from Just Radios for subs.

Hopefully that's the schematic and tube layout your looking for. Not the greatest in clarity but might be of some use. Let us know if it doesn't match.

This site seems to have one, although I note you posted this 3 years ago....
