sounds like a deal to meDron said:I eye-balled it with a ruler and it's like 47-48mm. roughly. The thickness of the metal is approx 2mm. Just judging by the state it's in, I would say it'll last you 5-7 years. But that's just a guesstimate. It's got resonator on it. A bit of rusty dust at the joining ends.... That's about it.
