4C collets (Crawford 122S) sizes 1/4 5/16 3/8 1/2 5/8 3/4 vgc lathe milling etc

4C collets (Crawford 122S) sizes 1/4 5/16 3/8 1/2 5/8 3/4. These are in good condition, four of them (1/4, 3/8. 1/2 and 3/4) are Crawford and look possibly unused, the other two are unmarked (so I am guessing the sizes) and used, but in good useable condition.
