I recently bought a house built in the 1930's with external pebble dash painted white. At various places there are brown rust marks showing on the paint. When investigating the cause of these marks I found there was an iron rod or 'spike' approximately 5 1/2 inches long going into the wall of the house (See photo). It is 1/2 inch thick, square with a point on either end.
I just wanted to ask for help in identifying what it is or what it's purpose is?
I think it is a support for a early floating render system, the spikes would fit into the mortar joint and support a vertical stud which would support a mesh and render. I'll check some books and see if I can find something
