Nice buy! A steal for that price!
an aside on the historicity of brass oculars:
I've been seeing new offerings with the brass cross underneath the ocular region...which I think is wrong as it isn't just decorative, it is supposed to strengthen that area of the helm. Saw one on sale for $175 (starting bid) but it don't look right to me.
The brass ocular thing is just a 'cheaper' way to mimic what people are seeing in manuscripts. Historically it was most likely real gold leaf or painting, but the underlying metal is steel on all surviving examples. The brass thing kind of caught on though, and has become a huge reenactorism.
