Does it have to look good

[Duke Speedy of Leighton]

Well... maybe 7.5% would do, ! My 6 x 15mm FOW, plus 6mm, 10mm and 25mm kit and Vietnam 15mm Jungles, so basically many tables worth, most can be moved between scales and tables at the moment cost...
slightly less than Bolivia's National Debt...
Actually, just googled that - ouch!
Good stuff is worth the investment,  it will last years and years if you look after it.
