To Be Or Not To Be - Harada That Is!

[jfa.series1]

I was recently gifted with a box of S30 antennas and associated parts. I hope to refurb them and get them in the hands of new owners. Of three antennas with mast bases, one is marked Harada and the other two have no branding whatsoever. The branded and non-branded units appear to be virtually identical in all respects, except for branding. Both have what might be a date stamp.

My question to the group is: did Harada produce non-branded antennas or was there another manufacturer involved building identical but unbranded units, perhaps under license from Harada?

The one on the right looks to be a Harada Model HA-100, which is a replacement antenna for the S30. 

The HA-100 typically had a cylindrical versus pointy tip.
