Wow.. your frame looks very similar to my frame ... I had mine built just as the pandemic was starting.
In similar, I mean the twin-top tube design. My inspiration came from the Vassago MooseKnuckle frame, but with custom geometry. I chose external cable routing, as I am not a big fan of internal routing and dealing with brake fluid.
Couple questions ...
Did Walty try to convince to not use two seat-tube to top-tube connecting tubes? They wanted to do it with one, but I convinced them to do it with two, but there was a 20-40 dollar fee. Even then, that is the only part of the frame where the mitering is sloppy and there is a fair bit of filler weld material.
How much of a discount did they give you on this new frame?
Cheers
