What is the Engine Turning pattern for an 810 dash

Here are a couple photos of an original sedan dash:





I recently bought a very nice one newly made from Felix DeGeyter.

Sadly I can't answer this question. But several members sell these engine turned dash panels as does Stan Gilland in Wellington Kansas or Doug Pray in Broken Arrow Oklahoma. I bet some members have spares too. Be careful with the type you purchase. Some are of poor quality and very thin compared to this original. The base metal is brass. Then chromed. Then engine turned. I noticed your panel is from a convertible too. Are you planning to engine turn your own piece? If so best of luck and please post pictures.

I can not clearly make out the pattern on my insert.  It does not look like the circles overlap half way like many other manufacturers used.  Do the circles just butt up to each other left to right without overlap?  Then is the row below it offset one diameter and then just touching the bottom edge of the circle above it?Thank you in advance for your help.
