Hello Red Neck Jedi
My name is Padraig O Ruairc and Im in charge of a group called Kakhi and Green who portray both sides of the Irish war of Independence. We have been doing this for about six years now. Id be happy to give you information on kit for the 1916 - 1921 period I presume its for the republican side. My first piece of advice is avoid the fancy green Irish Volunteer uniforms. While its easy enough to doctor modern military dress uniforms to look like the Irish Volunteer ones, The uniform itself was rare enough at the time. Most historians agree that duriung easter week 1916 only 25% to 30% of the rebels actually wore any sort of uniform. In the 1917 - 1921 period Irish Volunteer / IRA uniforms were even rarer (and a lot less fancy that the approved 1914 version!) The Volunteer uniform came back into vogue after the truce in July 1921 and was actually most widespread at the outbreak of the civil war.
What im trying to get across here is that you should wear 1920's civilian clothes if you want to be accurate. Try your local charity / thrift store for three piece suits and long civilian trench style coats in black, brown, or navy. Cordruoy was also very popular, look for cordruoy waistcoats and trousers preferably the same colour. Grandfather (ie collarless) shirts are easy enough to get hold of. Plain white is best but stripes in simple colours are also accurate. If you are doing city ASU then a collared shirt and tie are fine. For boots try the internet for WW1 British Army issue. For hats try to get a "Cheltanem" wide brimmed hat or "baker boy" hat in tweed or cordouroy try a hatters and formal menswear shop for these as you proably wont get them second hand - again go for plain colours. If you need I can give you the addresses of hat suppliers or shops that sell irish tweed jackets.
You can supliment the civilian dress with British ww1 and Boer War Bandoliers, Sam browne belts and leather lrggings or wrap around cloth putees. If you would like replica Irish Volunteer Belt Buckles or badges I know people here who are making them.
Id like to write more but im just back home after a three hour drive from doing a 1916 -1921 reenactment and its pretty late. This should have given you some ideas. If you would like more information or have any specific kit / history questions please e-mail me at firstname.lastname@example.org
Bye for now Ill checek this post again tomorrow.
