I have a vintage Delbana chronograph dating from what I believe is the late 40s to the early 50s. It's a great daily wear watch, with an interesting Venus 175 column-wheel movement that elevates it over the common Landeron-based chronos of the era. The 37mm case is gold-plated base metal (brass?) with long "corne de vache" bull's horn lugs giving it a 48mm lug to lug length. However, one of these lugs is the reason for this post: it is bent slightly downwards and inwards compared to the others, squashing the strap slightly. This luckily isn't very noticeable when when the watch is on the wrist, but does bother me to a degree. Do any of you vintage experts have experience in straightening such bent lugs? I've tried to do some research and found that the solder can apparently work-harden when initially bent and thus break when trying to straighten it, but presumably that depends on how much it is off axis. In any case, I do not want to break a lug off this watch, with it's gorgeous champagne-toned brushed silver dial and smooth chronograph functions. I've attached some pictures below where the bent lug can be seen; thank you all in advance for your assistance.
