Extra front crossmember

Has anyone come across a Series 3 chassis with an extra front crossmember before? I have just tried to turn the engine with a crank handle but directly behind the front bumper is a solid 2" box section crossmember that is stopping me from passing the crank handle through to the crank pulley. The crossmember does not look like it is a later addition to the chassis so I am wondering if I have an aftermarket chassis and why the extra crossmember was welded in. Has anyone else seen a chassis with an extra front crossmember?

Might be a support for winch?

Quite a popular mod at one time for RTV 4x4 trials as a mounting point for a solid front tow point for recovery. Had one on mine.

Both of those would make sense. It has heavy recovery eyes bolted through it and the "apron" between the grille and the front bumper was missing when I bought the landy so it probably had a winch fitted at some point.
