Anyone got a Philips multimeter PM2525, PM2535, PM2534 etc?

Anyone got one of these? And more specifically, the RS-232 communications module option PM9190? They appear to be extremely rare.

If so, a photograph of it would be highly appreciated!

I have a 2535, though just looked and don't have the serial port (never really thought about it as the '35 had GPIB buiilt-in and I'd not even really noticed the panel for an expansion card)

I could possibly get pictures later, if that's useful without the serial, but would help to know what you're looking for, if so.

I assume that is the version which has the PM9191 GPIB interface combined into the mainboard? No need to send a picture, but... You are saying this unit also has the serial option slot?

I have a PM2525 but, alas, it does not have any communications ports on the back panel, only a plastic cutout where something could populate the space. 

But that's OK with me.  Because I find the non-backlit display nearly impossible to read, the power switch inconveniently placed on the back panel, the 4-wire ohms function needlessly having to use the probe socket, the horrendous calibration procedure which needs to be done at two different temperatures, the rather bland specs, and especially the internal function selection switch which is run by a motor to be an example of how not to design a multimeter.  Of all the dozens and dozens of 4-1/2 to 5-1/2 digit DMMs I've come across over the years, this one is my least favorite. 

All my personal opinion.  Some people may not agree.  That's OK.

I'll qualify this with the fact that I've never actually opened up the case (picked it up on ebay as-is, expecting to have a repair project, but it just worked when I plugged it in.)

But, yeah, that's what it looks like from the outside. The GPIB is clearly integrated into the device and not a removable module as the connector is attached directly onto the back panel. There is also a blank plastic filler panel above that covering a space that seems to be the same size and shape as the picture of the serial card you linked above.
