that's weird, is that an official accessory or something cobbled together out of the helicoid extension and some kind of parts?

or maybe it's a 165mm lens that someone gutted and converted?

 

[Lachlan Young]

I believe they were made by Schmachtenburg for re-issued 150 & 120mm Imagon lenses for a variety of focal plane shuttered medium format systems in the 1980's. The tube is an extension for the 150mm.

 

[Vaidotas]

Yes, it was common thing in nineties these helicoid tubes to use LF lens on MF format.
I suspect they were way cheaper than brand new MF lens in that time, when almost every studio had LF outfit, but market demand was in favor MF - faster result, enough resolution.

No, it is not something cobbled together by an enthusiastic photographer/machinist. It is a single unit. If you have looked carefully, there are no markings of any sort - aperture, focus, etc. Not even the Pentax name. All these would have been present if it was a modified item.
I have not seen this specific barrel for anything other than the 200mm Imagon, and over the past four years, I've sold around a dozen of them, some including the lens, disks and hood.

Yes - they were made specifically for the Imagons which Schmachtenburg had Rodenstock re-issue. In other words, they are a top quality, dedicated component.

I've owned the 120mm and 150mm Imagons and they are wonderful on MF. At the time I used them with an Exakta 66.

Would be awesome on Pentax 6x7

No doubt that its precise machinery from outstanding seller
