I’ve just received my Crespo table—not the original one, but the model called AP/244. I read a post on a German forum saying that it would fit under the rear bed extension, where the original table is normally stored.
It is the same length as the original, but 53 cm wide instead of 51 cm. It appears to be very good quality.
My MP came without the mounting plate and brackets, although the threaded mounting holes were already there. I found that 1sternehotel.de sells the brackets and mounting plate as an aftermarket set. It is not original, but the price is still well below that of the original parts.
I now have all the bits and pieces, so I’ll see whether everything fits together tomorrow or sometime during the coming weekend. I also ordered some chairs called expander from a company called frontrunner. They seem to fit below the chair in the "metalpocket" very nice chairs by the way. Will update when tested.
