Good morning Ross
Thanks again.  Yes, this is a very strange entry.  I give details below plus the 3 prior entries as these link in, I think.
82/43         -     Swanton Morley        H      ?       23.04.43 (date of movement)
222/43       -     West Raynham (9)     -      -       10.09.43    
/                -     Swanton Morley         -      -            -
184/43       -     11s of TT                  H      B      09.10. 43
On the last entry, overwritten faintly (pencil?) in the first 2 columns is "W RAYNHAM PORS"
In the mustering column are the following related entries.
ut Inst. Rpn.  23.06.43
U/T SEW (2)    7.10.43
SEA (5)         28.10.43
Again any help would be much appreciated.
Subject to any further feedback from you, I have now written up my mum's war service, including details of RAF stations served at and with supplementary information and photographs.  It is a 23-page WORD document so can be transferred electronically.  Is there anywhere that this can be posted on line for historical purposes?
Happy to send you a personal copy if you let me have your email.  My email is 
bob.young@y-c-s.co.uk.
Thanks again for your help, Ross.  Very much appreciated. 
Bob
