Circular Sash Router & Circular Common Oveloe Router Tools

These are highly likely Preston, one is marked 5/8 Lambtongue which suggessts a Preston 1387B the other is likely a 1387D.

On all 4 Irons I can't see any Preston marks, please study photo's but I'm 99% certain these would be Preston.

Both used with chipped paintwork / japaning.
