A bit late replying I'm afraid, but the camp was on Arrowe Park Road by where the Royal Mail sorting office is now.
From December 1947 it housed 113 Assault Engineer Regiment Workshops. In the early 60s it was home to the 63rd (I think) Cheshire army cadet force. 2184 squadron Air Cadets are still on a small part of the site.
After closing the site became a British Telecom Engineering Centre, and then an HGV driver training centre. What remains of the site is now demolished, derelict and for sale.
I hope this is of some help, if anyone has any further information, particularly of its use during the war, or pictures, I would be grateful if you could contact me.
