Thermador Oven Part

I need a replacement part which has been discontinued by Thermador, and an article in the Eichler Network suggested posting a notice here. The appliance is a CMT21 dual oven where the top oven is both microwave and conventional. The part is an upper oven latch assembly, part number 14-34-568. I am told another number also applies to this part, 485808. I would be happy to have a latch assembly from a no-longer-used oven if a new one can't be found. Thank you.
