I can do that myself, but apart from one set at a frankly ridiculous price of 60 quid there are then hundreds of options that could all be pants, feel free to share a link for some you've bought that were up to scratch, cheers staff.
For 50mm Termis, they only seem available in 90mm and 110mm, the original one is below, seems to be 100mm wide so would be c110mm tall, the 90mm would be too small ...
I recon by the time you straighten your old knackered tape measure and put it to the actual edge you will be 110..
