Battery & Searchlight Regiment, Royal Artillery

Can anyone tell me what 542 means under unit column

 

Got it ,I missed the bat part
So that was the battery unit sent to straight from enlisting ?

 

What I'm trying to work out for someone was her father in same reg as my father as what it possibly looks like
On my father's it's 542 67th searchlight regiment 18/7/ 1940 would that be the possible date he was transferred to the 67th regiment ?

Thanks TD ...

 

Careful. May be typos but you're in danger of muddling 542 and 452 Batteries both of which are mentioned.
542 Battery was part of 236 Searchlight Training Regt.based at Shrewsbury, Shropshire.
452 Battery was part of 67 Searchlight Regt

ah right , I'll double check after work on my father's one , thanks Tim

 

Well spotted , mistake on my behalf , my father was in the 452, and the other person I was looking at was in 542

 

Not so.
The limited information given in your attachments shows:
#1 Enlisted 542 Battery 236 Searchlight Training Regt and transferred to Admin Battery for Agricultural leave..
Then posted 26/9/41 to 452 Battery 67 Searchlight Regt.
#4 Enlisted 216 Searchlight Training Regt, Battery not shown. This Regt was based at Abergele, Conwy.
Then posted 18/7/40 to 452 Battery 67 Searchlight Regt.
Better info probably available from the full Service Records rather than the limited scans you have posted.
Hope this helps.
