Pridolian Brachiopod ID - Eoplectodonta transversalis?

[Mainefossils]

The brachiopod fauna of the Leighton Formation is so small that I don't often find one that needs some help with identification. This individual does. The closest brachiopod that has the same characteristics is Eoplectodonta (=Plectambonites) transversalis, but it only occurs in the Dennys Formation. The Dennys Fm has quite a different fauna from the Leighton, but it is the closest thing I could find. My other option was some sort of small spiriferid. I will have to defer to @Tidgy's Dad for this one. 

 

Below are two pictures of it, first of the cast, and second of the external mold. Unfortunately, the fossil is rather damaged - the split did not cooperate with it. It is from the Leighton Fm, which is Silurian, Pridolian. 

 

Thanks in advance for your help!

Not a spiriferid, I'm pretty sure it's a stroph but no idea which one.

The ormament  such as can be seen  doesn't look right for Eoplectodonta, better preserved specimen required.
