Hello, my grandfather recently came across this knife and bought it. All my knife ID & Price guides don't cover the Rodgers England knives. I'd like some help estimating when it was made, and perhaps a ballpark value? I've found somewhat similar knives and tangs online but would like confirmation from those with more knowledge.

closed length is 3.5 inches
3 blade split-back whittler
stag covers, bare-head (no bolsters)
all blades stamped front side and rear side

Main Blade front "RODGERS CUTLERS TO HIS MAJESTY" and rear "ENGLAND"
Small blade #1 front has Star & Cross and rear says "RODGERS CUTLERS TO HIS MAJESTY"
Small blade #2 front has Star & Cross and rear says "NO. 6 NORFOLK STREET SHEFFIELD"
