UPDATE: This Klann compressor has been long gone, sold back in 2004 when the thread was posted. I just received a question about it, sorry I forgot to update this thread at the time, ooops.

I occasionally have an SPX compressor kit for sale, made by Klann, click here for details. It does not include the large compression plates or the carry case. It does fit through the chassis hole in the W123 without cutting / grinding, unlike the cheap Chinese clones.
