My guess is
Item Code 5 (1976) was the first release of those tables, but I cannot confirm that.
Item Code 5 are Ready Reference Charts, which were of course the predecessor of the Ready Reference Book.
Dated 1976
But in the three pictures/scans offered for each printing of them on the Judges Guild pages I do not see the Weapon Priority Chart.

The Judges Shield (1977) includes the Weapon Priority Chart on one of the sides of one card/page.
The site states they are Sheets (thin paper?) but mine are thick double sided heavy card stock... real thick.
Item Code 28

The Loose Ready Reference Sheets also has the Weapon Priority Chart.
(Specifically Sheet J - 5)
Item Code 14, which was included with Installments J, K & L
Dated from 1977
Cover Sheet for the Ready Reference Sheets package

Sheet J - 5

I can confirm the two Items Coded 14 and 28 DO include the Weapon Priority Chart as I have copies of both of them.
Plus the scans/pics on the JG pages confirm them as well.
