Hello,

Not all such markings will be associated with assembly work in the strict sense. Some, for example represent the signiture of the laborer or workshop where the joinery was cut, assembled and dissembled for transport to the building site. It's not unthinkable that some would label individual parts but more commonly the markings are part of a system of matching two non interchangeable parts of a joint in a complex construction.There are also marks associated with felling and transport though these don't always show up on the finished timbers.

Recently attaching an image has become a problem for me on this web site. I wonder if something structurally has been altered or if I am the only one experiencing this.

Greetings,

Don Wagstaff
