Adjustable rocker arms identification

[broughj]

I have a set of adjustable rocker arms that were on a set of J heads. Was thinking about using them on a 340 build. Have not been able to figure out by searching this forum and other internet sites if they are original MOPAR items or aftermarket. Initially thought they were original 273 parts, but they have lock nuts on the adjusters.

The only markings on them are shown in the pictures. A triangle shaped logo on one end and a single- or two-digit number on the other end of each rocker arm. The rockers are not bushed. I did notice some wear on the one rocker that I removed from the shaft, so perhaps they are not useable. Any ideas what these rockers are?


Thanks for any help you can provide.

I’ve used Crane rockers that looked just like that.

I believe they would have also been available thru MP.

Look like Crane. Their complete adjustable kits came with spring separators like that.

Here are the Cranes I have. Look the same.

They are crane. I have a set myself and had a thread about them a while back.

No markings. Crane it is thanks everyone

Thanks for the underside picture, definitely aftermarket. Not sure what brand, but if RRR says crane, I'd go with that.
