I think where the confusion comes into play w/the B. C. Miroku made guns most often seen is many people wrongly think the 'field grade' was the plainest version and all field grades have ejectors. The 'Venture grade' was the simplest & least expensive version and they all have a one piece extractor fitted between the bbls.
Put another way:
Venture grade = lowest grade w/minimal engraving centered on action sides; extractor
Field grade = Nice engraving over most of action w/ejectors
Superior grade = more elaborate engraving w/def. curve in pattern on action side & whot resembles a stippled pair of rams horns when viewed from the top; ejectors.
