My Grandfather had a skilled background therefore the R.A.F. wanted to make use of it. He was stationed in Blackpool. Prior to World War 2 and serving he lived in Brechin, Angus Scotland. I am trying to find out where he would of taken his training. There was apparently a Barrage balloon training groundon an estate in Brechin. This no longer exists however. He was shown on the Muster Roll for 1941 as being an Instructor. The R.A.F. in Sleaford has no record of him. How could I find out about where he trained in his home town of Brechin if it no longer exists as there must be a record out there for him?
