1966 Cat 933 With Backhoe

Hi,
Im considering purchasing a 1966 933 and it has a backhoe.
I did search here and elsewhere and I cannot find another fitted with the backhoe.
I was wondering if anyone here knows if this is a Cat hoe or some aftermarket item?

I only looked at the machine on the ad, [attachment=58944]cat933.jpg[/attachment][attachment=58945]cathoe.jpg[/attachment][attachment=58946]cathoe2.jpg[/attachment]

Thoughts?
Expert knowledge is appreciated.

My thought (it is a guess) is the backhoe was built by Wain-Roy. I believe they supplied attachments to Cat before they started making equivalent machines of their own. It has the structure of a Wain-Roy if I remember correctly.
