Wagon Steering box

[DaveyC]

I'm looking for a steering box that is suitable for a 7 ton (Fowler) wagon with solid tyres.
Here is a picture of what we have already.


It is not the original steering box, and there are suspicions that this one is not up to the job. And its broken. So make of that what you will.

We managed to find a chap with a spare for his Sentinel, which seemed like an ideal replacement, but alas, he would not part with it. Which I can understand.

Even if someone has something which we could loan, until we find something, we would be eternally grateful.

Or better still, if someone had the genuine Fowler article, I would happily come and lick hot clinker from your fire-grate.
That sounds a bit rude! I didn't mean it to, But you get the picture.
