Who Manufactured the Revonoc plane?

I have just acquired a Revonoc plane, thinking that it was a Stanley No. 23 transitional plane, prior to cleaning. The markings are now clear. Except for a Revonoc marked thick tapered blade and the Revonoc stamp in the front, it is indistiquishable from a Stanley No 23. Other sources also credit Stanley, and in my view is in fact made by Stanley.
