Ransomes one-piece disc clamps

[Farmerpickle]

Afternoon all,

I am asking this question out curiosity. Do you know what they are off of? The one on the right I believe is off of a TS 90. This one is around 4”.

The one on the left, which is highly sought after, I believe came off a Robin as it is a touch under 3” (too small to fit on a TS59 frame or TS86 unless ground down).
The question is where do these 3” clamps come from? What ploughs were they originally fitted to? The only plough I can think of is a Robin. Were they an optional extra?

Would that size fit a trailer plough frame???

I didn’t think they were on Robins, I thought they were off newer ploughs... I have them on my Robin, because the standard holders are hopeless with the two eye bolts...

My TS81 has the smaller ones fitted.
