oooh - you're not going to like the dozens they skipped here - totally worthless as anyone still using one has one, and anyone not using one, uses faster, more accurate, easier to use, more modern CAD and doesn't want one.
Don't even have the single one kept for older drawing updates, as any update will involve converting to CAD - never mind no-one still has a selection of different dia leads, squares, curves, pens, knofe blades for scrapping off . .
MOD - I think this should be in the "Vandalism" thread - do you want it moving?
