Is this from a carrier

[Ron Pier]

I think it's a vehicle prop shaft joint. I have similar looking on my Morris Commercial but it has rubber joints. Whatever vehicle it's from must have more nipples than the Luton Girls Choir!! Ron

Hi David yes its a carrier duplex coupling conecting the gearbox to the diff

Ron P. Some of us are now waiting for that particular picture
Ron W. because these are such complicated pieces of engineering did they last well?
And..... were these early production, replaced with the rubber bushed type?

Hi Lynn, not trying to answer for Ron but regular maintenance on this particular joint is paramount, it states in the maintenance book that not greasing even one nipple is just as bad as not greasing the whole joint at all. It is quite a complex part if you ever get to pull one apart and you can certainly appreciate why it requires so many nipples In my opinion, I don't think it was an early production joint as I have seen them on late model carriers as well as early ones. Like with most things, I think I would have came done to parts availability at the time and also manufacture preference as to whether to use this coupling, the 8 point coupling or the muff coupling. From memory the 2pdr and 3' mortar carrier use the 8 point coupling in there drive lines.

I have seen muff coupling pictures, but never in the flesh. Were many used?
