L31 WB Ute

[Innuendo]

Despite some body issues, you must be tempted WB? Out of interest on the thin tag the "L" where I'd expect the engine code on HQ-Z tags to be 202, did the position or code change for WB?

308 in a WB had WT as the engine prefix so "L" would be incorrect as the 308 identifier and like you said it points to a High Compression 202 it should be a "T".
But there is no disputing the L31 on the other tag.
