Ian states – The NETTLE D 8468 as per the link above was found a couple of weeks ago and beyond it being a Side Arch it wasn’t obvious what the numbers meant. Now that this slightly different NETTLE-D 84 68 End Arch has turned up we might make progress?

Number like 84 68 should refer to the inner and outer diameters of the brick circle they form but with 9″ bricks and a difference of 16 that seems unlikely. Quick work with straight edges says these bricks form a circle with a diameter of about 60″ not including any bonding cement so 68″ with bonding cement is not impossible. Where does the 84 fit in? That’s 7′ so if not the outer diameter, is it the height/depth?
