I have just found out that the Graseby MR10 is now obsolete with nothing to take its place, only discovered this when trying to get parts to repair one we have here. I know it is a long time between posts but I have found an alternative (you probably already know) but for anyone out there who does not there is one from Central Medical Supplies (

Shame really as the MR10 was a bit of history, I've seen 3 versions of it since I started here some 24 years ago. If anyone does have any parts they don't want though, especially a complete front case (labels and alarm dome/cover) it would be gratefully received.
