I'm pretty sure it's the later version then as the cap is the same size as on my new one. In any event, I don't have a heavy or coarse beard so I don't have too many shaving challenges.If you don’t have coarse hair you may not notice the difference even if yours is the more aggressive one. They both shave exactly the same for me but the old EJ89 shaves noticeably closer on my neck area where there’s always a touch or black left even with the most aggressive razors. On my cheeks I couldn’t tell the difference.
If you look at the blade gap side by side with your newer one it would probably be apparent if your older one has a wider gap. But also the top cap is narrower in both width and length over my newer ones. I have measurements I took with calipers written down somewhere. Again the top cap is probably noticeable with the eye if you look at it from the side if it’s one of the more aggressive ones.
I have no idea what year this one is since it’s a relatives and he doesn’t know the exact year he purchased it but it was soon after it came out which I believe was circa 2009-2010.
