Advice: Omega MG-1170 - Cal-5390 Split Second

Hello there,

I have a question ...

I posted the same question already, but don't remember where I posted it.
I give it a try for the second time ...

I am from Belgium "EU" and need some advise ...

Concerning: Omega MG-1170 - Cal-5390 Split Second in original box and label.
I like to sell it and don't know where to offer it to the richt collectors.
Is any one here on the Omega Forum who can advice me in this matter?

By the way ... I have 2 of the same Omega MG-1170 - Cal-5390 Split Second, but the second one is not running but looks great ...
I like to sell both Omega MG-1170 - Cal-5390 Split Second for the price of ONE ...

*These Omega's MG-1170 are from firsthand.
*They both are belonged to my father ... probably he had them over more than 50 years.

Any reactions or advices are welcome ...

Thank you
