Erson Camshaft

[Coopa]

Hi all,
Does anyone know about Erson cams Ive just pulled my 186 apart for rebuild and found this cam, I did a bit googling and have found a bit of info on RV-15-h cams but on in V8's, I assume it's a mild cam but would like a few more details.

Any help would be appreciated
