I left the measuring tape there, I thought that was close enough, but I i will be sure
to write down the measurements next time, duly noted!
There is a round flap of leather covering the back of the turn lock hardware, yes.
Not sure what you mean by a macro close up but I am sending more photos of the creed if the other was not clear enough.
There are no markings on the brass buckle, which is thin like the one in the photo you put up on the suede/leather combo bag - the strap is the same on mine.
Oh, and the only markings I found is on the little chain, on the clasp it says "bead chain".
Had to use a magnifying glass to read it, I am getting old!!
