Does anyone recognize this Durst(?) lens board?

Found this in my junk pile. Will not fit Durst 606 unfortunately...too big at 85mm diameter. My Durst 606 is about 81mm. It is a recessed board at approximately 18mm. Has a 39mm thread. Its all black and only has "A" stamped on the inside.

LPL ?

Luis is probably right as it looks more and more Like a Saunders LPL lensboard. In doing some research on one site that makes custom boards it said the outside diameter is 84mm which is a match to mine as my measuring tool is cheap plastic. Is there someone else who can confirm this?

It is an LPL lensboard, used on the US numbered 670 and 4x5 models.
