WiFi ADSL Modem Router (Ruddington NG11)

I have a used Plusnet internet ADSL modem WiFi router that needs a new home.
Made by Sagemcom, model number 2704N.
I believe it can be flashed with Open WRT.
Not been used for some time and is untested but it was fully functioning when last used.
In good cosmetic condition.
To be collected from Ruddington.
