No flack from me I'm 100% in agreement. My bevelled edge is 5/8" thick came from Vickers tank factory and would cost more than a small car today and weighs nearly has much. It also has stamped on it working temperature range it's accurate at and it's quite narrow, it will also be fair way from calibrated by now so I treat it with kid gloves and it's away in it's wooden case ASAP.

You get what you pay for.!!
