Help Bass String Brand ID

[Ham Rex]

Hello:

Can anyone ID the brand of these taper core strings? They are .130 .105 .85 .65 .45 as far as my dial calipers report.

They have a hex core at center.

B E A D strings have taper core.

The silk appears to be gold or yellow. 

Thanks for your help.

Gold silk wrap strings are rare and the only ones I've ever had cross the repair bench were DRs.
