Early Rolex--cannot find on RANFFT

[LittleWatchShop]

Got this a lot of this and that.  Searched Ranfft with no success.  Found on ebay identified as "Oyster Royal Sub Second 10 3/4"

Anybody know anything about it?  Listed for about $600 on ebay.  Mine is missing balance so it has much less value IMHO.

Are there any markings under the dial?

Just a number...didn't write it down

That might be the caliber number, have another look.

Looks a lot like something in the 700 series.  I'm not sure about that pallet bridge. That's an odd one. Certainly distinctive. I believe the 700 is a 10 1/2 ligne, FWIW.

If not exactly the same caliber, its a variant of your piece.

That is it I think.  I confirm the dial side.  I guess it doesn't have a classic caliber number.

 FHF30 and its variants is place to start with,  of many variants made, you might see only a few on  ranfft's site, parts mostly interchange so there is good chance of finding  the ones missing in you piece.

Oh $600 is way too high, notice Rolex adjusted them  which this piece is missing.the balance.

Many manufacturer made 700 series MrRoundel mentioned above, I a am not sure if its the same story with caliber 30s. 

Just to give you an idea ,you can get a healthy running fhf70 for about fifty bucks.

Good luck pal
