You can get them (see photograph). The trouble is I can't remember where I got mine. It's not RAF, but it looks like UK Civil Service Stores. I suspect it must have accidentally fallen into my nav-bag on some occasion. Still if the Civil Service requisition them, they must have been produced by an instrument company somewhere.
However, why not just draw a minutes scale with Indian ink on clear thin acrylic sheet (available from a good quality art shop, and stick it under clear Perspex. Alternatively, you could mirror write it in Indian Ink under the Perspex (see Photo) and cover it with Sellotape to protect the scale. DaveP
