WEM never actually made any keyboards, as far as I’m aware, but they did distribute some in the UK. An example of one of these, the Teischord C, has just joined my WEM collection (June 9th 2019). It needed a bit of TLC but basically works although I don’t think I’d ever want to use it on gigs.

I believe the Teischord C also dates from the 1960’s but I can’t find any documentation to support this.
Here is the image of the Telstar –
