drivers view on tiger 1

My opinion?  Leave it as is:  The gloss would exaggerate a 1/35 piece of glass' finish.  As to any blue tint -- the actual glass had none -- modellers feel compelled to add this to mimic the tint that sometimes appears at different angles.  For your driver's block, I'd leave it alone.

Ye, agreed, leave it be. The glass in cupole's will often be periscopes, so i think this is why people feel the ned to tint them. The drivers block is just a thick piece of glass.
