Hi Folks,
This has proven itself to be a fantastic journey for me during the past week. I have learned so much about my old home town that I left over 40 years ago from your replies and indeed questions because each one has opened another door which I was only too eager to enter.
None more so than today when I visited the Garda Museum based in Dublin Castle . On my arrival I was greeted by the curator Gerry who was a mind of information about his charges and particularly of the Dublin Metropolitan Police of which his Grandfather was a member.
The only problem being his knowledge of the force’s history has opened the whole issue of the date of the photo up again. As was pointed out here the Garda Siochana (Guardians of the Peace) was founded in 1922 when this Country gained her independence to replace primarily the Royal Irish Constabulary. A second force, the D M P, were given some autonomy and allowed to continue for three years before having to decide to amalgamate with the new body or disband. In 1925 they agreed to join but on various conditions one being that they be allowed to retain their uniform which included the ‘Bobby’ type helmet. The new Government acceded to this request only on the condition that the hat and button badge be changed to reflect the new force. The uniform agreement only applied to existing members of the Force and all new recruits were issued with the new and very distinct Free State uniform. The Curator decided, if he was to err it would be on the wide side as depending on the age or the recruit on joining prior to 1922 the uniform could easily have been worn up to the 1950’s as pointed out by fia, particularly for ceremonial occasions. He would also rule out (hesitantly) anything from the 19th century because of the style of great coat. So there we have it, a very loose time span between 1900 and 1950 -ish. The fashions have tightened the time span and close ups of clothing as has been requested might reveal that little snippet that will bring this query to a close.
Heywood has suggested yet another line of enquiry for me and I hope to visit the National Photographic Archives in Templebar on Monday in the hope that C Neville Cook’s collection are housed there. And Nailer has agreed with the many on here who felt the photo had to be pre 1925.
This photo is of the Garda Siochana helmet incorporating the Gaelic intertwined lettering of G and S and replaced the badge previously adorning the helmets of the Dublin Metropolitan Police.

So now, as suggested by PruM in Reply #159 on page 16 I will repost the photo and ask for it to be ‘dated’ and move forward from there.
Thanks again Folks, excellent work and I hope to see you all over on the new thread
