looking for tri-compax parts

hi OF,

i am new here. Nice to meet everyone here.

i like vintage watch, and have collected a few omega and universal watches. most of them are without complicate functions.

Last week I just bought a vintage tri-compax 22283, cal.481, produced around 1950.
However, the crown and calander sub-dial hand looks like not original, and i want to replace it. i have looked through ebay quite few days, but still no finding.

Any idea where i can find them?

Also, if u see any parts suspect not original pls let me know, i am willing to learn more.

thanks!

additional info, i think most of u recognize this piece, i bought from bonhams few days ago. it still in shipping.

the bonhams condition report says "crown maybe not original", but for me it looks more like overused.

i am more worry on the calander dial hand, coz so far i never see this kind of thicker hand on tri-compax, and it should be red right?

Anyway, i still willing to pay almost 8k usd for it include tax and shipment. i love the sesame shape marker. and the dial looks nice and origin. Just never expect it is so hard to find spare part.

thanks, i will slowly try find the correct hand in following years, but not in a rush.

Beautiful watch, congrats!
