Bricks and Salt

 

The bricks on the left are the new brickwork on the stud offices and those on the right are those on the house fifteen years ago.

 
Why has one set got salt on the outside so quickly and the other never has had any?

Could it be that the ones on the house used a recessed joint using a tool called an Excalibur Pointmaster? I used to own the company until I fell foul of a typical insolvency stitch-up which left me with the debts of the company and none of the assets.

But I do have a few Pointmasters that I sell occasionally on eBay.
