Well I'm pleased to be able to report that the RA218 ISB adaptor has arrived with Ian in Edinburgh direct from the eBay seller who is in Manchester, thus saving bouncing up and down the UK.

Ian tells me that all the rather rare and special glass encapsulated crystals are are still present - they often get pilfered as spares - and we've located replacements for the two circular Plessey connectors on the rear panel that had been replaced by 'chocolate blocks', so some degree of originality can be restored :)

I thought that I'd located a suitable 19" rack  locally to house all this gear but modern racks only seem to take 400 mm front to back depth  behind the panel - the RA17 needs 480 mm :(

A server rack should do you fine - they're usually 800mm front-to-back, plenty of room for 480mm deep kit.

As an example: https://www.ebay.co.uk/itm/12u-Server-Rack-cabinet-600-W-x-800-D-x-634-H-Glass-Front-Door-Flat-Pack/191869787799
Cheers!

Thanks Ade,

I've looked on line at a few server racks, and the few that give the vital dimension between the front and rear vertical rails all have proved to be no more than 400 mm :(

That one may be deeper I'll ping them a question

Hi there, Andrew,

Should you decide to home-brew a 19" rack, I have an Imhof catalogue somewhere in my filing 'system' that might have any dimensions you need.

My last experience with 19" hardware was complicated by ensuring consistency between the mounting screws and the cage nut - the options were 0 BA, " BSF or M6.  That's the recent 19"-lite, the traditional was 0 BA tapped holes in good old solid mild steel angle.  Imhof must have had a standing order with the tap manufacturers! 
Best regards,

Pete W.
