Pte Edward Rush, B Coy, 4 VB and 5449, 1 VSAC, Norfolk Regt arrived home 16 June 1901 with the first returning Volunteers. If engraving is limited to the first returnees to Norwich as you have wondered, Rush might be expected to have an engraved tribute medal. The attached suggests otherwise.
On the other hand, Pte Walter Albert Rush C Coy, 4 VB and 5542, 1 VSC, got home 12 August 1901. Different companies but adjacent numbers in the roll...might Walter’s and Edward be related and it is Walter’s medal described in the clipping?
