Hi,
I recently found a set of
flats I had laying around and the original packaging is lost. Will appreciate any help identifying them for comparison purposes.

Standard length (34" scale), set of 4
The ball-ends are all brassy-colored metal (no paint), no silk wrap at that end, but dark blue wrap at the tuner end. They're pretty fat and high tension. If anyone may have some idea, that would be great!
Thanks in advance.
Bill
