Want to Buy WTB: LPL C7700 / 670MXL Mixing Chamber

I bought the enlarger in early August from a UK seller, unfortunately the seller didn't include the "Mixing Chamber" for the item . Although I have requested it from the seller, and he promised to send it, the item is still forthcoming.

So, appreciate it if someone happens to have a spare "Mixing Chamber" for the above enlarger, could you please give me a buzz. I'm located in Kuala Lumpur, Malaysia. Thanks.
