Chugalug,
My Chinagraph (pencil-sharpener-able old type), was supplied by WHS not all that long ago. They were the original RAF issue type (the posh "propelling pencils" came in later - I kept a couple of these for a few years after I came out, but they're gone now).
You had to be careful with the old pencils - if you tried for too narrow a point, it would break off. Whittling would be tricky, I'd think, unless you had a
very sharp knife.
Why have our Posts gone all fat again ? Or is it just my laptop ?
