Below are the flags I used on Gordon of Monymore's Regiment. They were made in photoshop and can be printed for use in your own armies. They can be used as is, but I prefer to re-paint completely over the printed design as I prefer the hand-painted look. The hand-painted end-product can be seen here.
The white sheet above is a Colonel's colour with the Gordon coat of arms in the centre. There is no direct evidence that Monymore used this colour, but Stuart Reid and others have postulated that this is likely given the later use of this colour by the Gordons of Strathavan during the Jacobite uprisings of both 1715 and 1745. The only difference between the English Civil War colour and the later colour would be the ducal coronet (or crown) placed above the arms signifying the title of Duke, granted in 1684 to the grandson of the 2nd Marquis of Huntly.
The Gordon arms are quartered, with each quarter representing Gordon territories or family branches. The first quarter is in the top right and blue field with three golden boar heads. This quarter represents Gordon. The second quarter is a gold (yellow) field with three red lions' heads. This quarter represents the Lordship of Badenoch. The third quarter is gold (yellow) with three red crescents, set inside a royal double tressure (or border). This quarter represents the Seton family. The fourth quarter is blue with three stylised five-petal flowers (referred to as cinquefoils). This quarter represents the Aboyne lands. More information on the Gordon coat of arms can be found here.
The yellow sheet is a speculative company colour based on a description of a set of colours ordered by Huntly in early 1644. The text and device is described by Spalding but the field colour is speculative (yellow seems likely for a rampant lion).
"Upon Monday the 15th of April he [Huntley] returned about six hours at even to Aberdeen he caused make some ensigns where upon ilk side was drawn a red rampant lion having a crown of gold above his head a 'CR' for Charles Rex having the motto 'For God the king and against all traitors' and beneath 'God save the king'. There were diverse others made for the barons. The marquis and his followers wore a black taffeta about their craig whilk was a sign to fight to the death but it proved otherwise"

There is one curious line in this quote; "There were diverse other made for the barons". Spalding could be saying here that a range of different flags were made for "the barons" (which I assume refers to all the nobles that fought under Huntly) . However I have interpreted this to mean that a number of similar sheets were provided to all Gordon regiments of 1644. This would include the Strathbogie Regt and Monaltrie's Regt, which later split into Inverey's Regt and Monymore's Regt in early 1645.
Apologies for repeating info on the yellow sheet that is posted elsewhere on this blog, but I wanted to include all the relevant flag information in this post too.
