Darren,
I am sure a wee bit of filing can remove one of the chinstraps, allowing the customer a choice of above the peak of the cap or under the chin. Allenby, the divisional commander, was a stickler for under the chin, but some Tommies still wore it on the cap, drawing a fearsome outburst from 'The Bull."
It is a fantastic figure, with real character and atmosphere. Don't dare withdraw it.
Best wishes
Chris
