Pair of Adjustable Rear / satellite speaker stands - black ?

Pair of black speaker stands suitable for rear or satellite speakers, I think the make is atlantic but am not sure bought them from Argos about 4 years ago. The stands are adjustable in height from 66cm to 122cm, the base is a triangle shape 36cm wide and the top plate measures 15cm square. They are blsck metal and in pretty good condition, you can see from the photos there a some marks on the top plate where speaker were attached and few scuffs on the feet. Not sure what weight they would take I used them with mission 78ds speakers which weigh 4.49kg. Buyer will need to collect from North London
