I just thought I would share my thoughts and approach to the unit so far as I am sure others out there might know a good deal more than me about this or can provide additional information or thoughts.
Obviously I am trying to model what the regiments might have been like at the time of the battle of the Boyne.
Uniform
I am assuming in general that all Inniskilling foot regiments will essentially have the same uniform
For Tiffin's regiment Walton states the unit had (lifting this from the sixteen ninety) blog: “Inniskilling Foot” grey coats. Grey coats in 1689. Two companies’ worth of red coats obtained in 1689.
Walton also taken from the sixteen ninety blog:-
Lawson on the other hand provides this as the uniform “First Regiment of Foot of Inniskilling” red coats, blue breeches, waistbelts, blue surtouts lined blue.*When they [the 27th] had reduced a body of James' troops to surrender at Belturbet in June they made it an especial condition that the enemy should surrender all the 'red coats' they had: and they obtained on that occasion enough red coats to clothe two companies; but when they got their new uniform from england it turned out to be grey." 66
I believe this is based on what was 'ordered' for the regiment.
I have decided to tend towards Walton's description for the uniform of Tiffin's and the Inniskilling foot in general and paint them as a standard unit
My approach is going to be to paint the units lightly militia style look in grey coats of varying shades, something similar to the what is in the image below (this is on the royal irish rangers website but I don't anything about the image itself).
i.e. grey coat/cuffs (of varying shades, maybe the odd brown thrown in), off white cravat, black or brown hat, grey or brown breeches and grey wool stockings.
Officer/Ensigns I plan to paint in a (dark) red something like the mounted officer in the picture.
For Tiffins unit I am considering adding in some red coats to represent the captured coats from Belturbet (maybe around 4 figures)
Other images of interest
I found this depiction of the uniform on the Inniskilling museum webiste. It also points towards grey but does seem to maybe be using some artistic licence on the colours
The museum also has this as an image in the uniforms section. I am taking it as a sample of what one of the shades of grey may have been like
Unit Type
I did IM Barry a little bit about this but, I am thinking of adding in more pike for some if not all of these units. I am sure they would have had some muskets especially given the loot from Belturbet.
In terms of Tiffin's regiment. I am still debating whether to have 3 bases of shot and 1 pike or make the command base, pike as well.
Flag
I did find an earlier discussion about this on the forum in which the only real flag suggestion for the unit was the St Georges Cross. At present I am thinking one standard bearer holding this, unless anyone would have other flag suggestions?
