Original steering wheel - by year

[chewiebarker]

Ignoring the steering wheel cover in this pic, can anyone confirm whether the wheel pictured is the shape/style of an ORIGINAL 1971 Suburban steering wheel?

I have looked at some of the contemporaneous brochures, but steering wheels are not depicted very prominently. It appears from those documents that I have seen, that there was a 3-spoke version and/or a version with an thick, angled bar across the middle (similar to this pic but without the additional hump where the horn button is).

Did steering wheels vary by model (k20 vs c10) or did they only change by year - and, if so, how often?

Any guidance would be greatly appreciated!

Thanks
