[Non-Ford] Help with Manifold ID, Please

[Citroënbender]

WW manifold, I believe off a Holden red motor (no anti-pollution fittings). Visually looks like a 186S or GTR manifold but part number of 2819553-P is not the same.

I can only source one reference to it using Google. Could it have been from a non-Holden vehicle (eg, a Bedford)?

Yes, it is an HR-HK-HT-HG 186S inlet manifold, they are also from the 161S/173S LC GTR.

There were several different casting number, but I've never noticed any real difference.

Thank you. I’m going to assume the atypical casting number makes it of lesser value, as not so universally sought.

Interesting
As Terry mentioned these are casting numbers, not part numbers. Usually the part number is similar, often just differing by the last digit.
But I wonder if a completely different number could perhaps indicate it was cast in a different foundry???

Nah, you just claim it's a super-rare "Bathurst" version, and ask twice as much.
