My father was in the RASC as a Fitter/Vehicle mechanic. He survived Dunkirk and later was a trainer on the amphibious craft in Portsmouth leading up to D Day. However, we know that he was stationed at Langford Lodge in Ireland in May 1941 (my mother is still alive and says he travelled back from Ireland for their wedding) he was there at least until the August 1942 when he was posted to Kensington. We have a photo of him doing guard duty at Langford Lodge. His service record reads 56[sic]/1/41. 3 Corp Petrol Park. Posted to 3rd Corps T+ps (I am not sure if this is transcribed correctly) Pet Coy then in the following 'dates' column - 19.9.41 26/3/41 Passed TT fitter Class 1 31/4/41 Unit transferred to 3 Corp w.e.f 26.9.41 3CTPC 13/1/42 Attached to 5 Corp HQ w.e.f 18/8/42 Posted No 2 ST Coy RASC w.e.f Kensington I have failed in my attempts to upload the relevent pages. (Newbie) There is more of course, (he seems to have gone back to CTBA 3 Corps in Jan 1942) and a stamp which says Workshop & Corps Troops Petrol Coy. but I am not sure that it would add anything to my questions which are :- Does anyone know what he would have been doing stationed at an airfield in Ireland before the Americans were even in the war and secondly, what do TT, CTBA and w.e.f. mean? (None of which are given in the abbreviations sent with his records.) I have spent quite a lot of time looking and can only find information about civilians from Lockhead being at Langford Lodge. Thank you for reading this and even more thanks if you can shed any light on it.
