Holden red engine prefix

Hello all,
Recently enquired about an LJ GTR over the phone. Asked if it had the original block - said he didn't know. Asked what the engine No was and he quoted WL as the prefix before the engine number. I thought GTR's used the JL prefix. Anyone ever heard of a 202 red with WL as the prefix? Any ideas welcome.
Regards, Ron

WL is 202 out of WB. I believe that would be a blue (12 port) 202 as well.

JLs were in LJ GTRs but also optional across all LJs from 73 on.
