TB22
Midfield
Had mine a couple of years ago in section 22 / They are only slip bricks ( sort of half thickness) machined off site and cemented into any vacant panel when they have a few to install . I think about 22 000 installed and panel numbers run from section one at the main entrance to about 30 clockwise round the SOLdaft question but i'll still ask, do they chisel a name onto a blank brick or cut out a brick and insert a pre chiseled one in ?
