Gruen Master

Anyone have a new mainspring for a Gruen 707 they can sell me? '48 catalogue shows dimensions of 1.90 x .12.5 x 320. which i believe converts to 10 x 9.5 x 12.5 in Dennison size?

Doesn't appear to be interchangeable with any other model than the 7 jewel 713 (which i've never seen).

Still here....
