There were never any photos of any smaller valve chest. The cylinders are replacements to the OEM and only offer a larger bore. I was the one that posted the photos. The only difference on the prototype vs the production was front cylinder covers have a recess on the inside of the bolt circle.

 

Here are the orignal photos.

 

 

 

 

Hi Richard,

Sorry, I should have posted a picture of the cylinders with the valves attached here is a couple pictures of the assemblies after painting.

Here's the link to Milton's page on oversize cylinders.

Not done this before so hope it works.

As happened before, when going to the supplied link, no cylinders were to be found. However, I rooted around and found them.

 

 

The website uses frames, so the posted links always take you to the wrong page. 

 

These cylinders appear to be a direct replacement for the OEMs.  So you just drop them in and bolt the orginal steam crest back on? 

 

My son and I came across an almost new Ruby the other day.  I'd like to machine my own cylinders, so just use the old one as a pattern, I guess.

 

Total Ruby newb here

 

Thanks for posting this, Bob
