Target

This is the shutter spring of a Target Brownie Six-20. (Cleaned up and in the extra.) I've been down a Brownie rabbit hole. Typically there isn't much about this one on the web and unlike others (the Brownie Target Six-20 - yes its all in the name, Brownie B,C,...) you can't just open it up and fix it. Fortunately I've managed to stick the viewfinder mirror back in place and give it a bit of a clean and it seems to be operational, although the only key bit I couldn't get at was the lens which does need a clean.
So, some film (620 AKA 120 on a 620 spool) is in the post, it will be interesting to see if it takes images, is lightproof...)

Ed. The results are back see here.
