Constellation seconds hand for 14381 and 2852

Hi all, I'm looking for a steel seconds hand for my cal. 551 ref. 14381 and another steel one for my cal. 505 ref. 2852. I saw some 066UZ1365 but these are 12.6mm from hole to tip and thus need to be shortened with 2mm as the one I need (066UZ1355) is only 10.5mm from hole to tip for piepan dials. Would prefer original Omega ones, so the ones that are not riveted. Patina is not an issue so if someone has some donor parts somewhere that they would want to part with, please send me a PM 😉
