Estimate value

[russell16688]

I recently built the pictured bike and had it resprayed at Cromaworks. I absolutely love it but we’ve just had a baby and I potentially need a clear out and some funds.
Could someone help me value it to see whether it’s a worthwhile sale (albeit a reluctant one)

The specs are:
Frame: Ottadini Reynolds 531 pro frame. I believe a 22” frame (around 53cm)
Wheels: Wolber profil 20 rims on Shimano 600 hubs
Rear mech: Dura ace 7400
Front mech: as above
Brakes: mixed Shimano 105 front and campag chorus rear
Levers: Tektro aero levers
Finishing kit: Deda
Saddle Concor.

It’s a beautiful bike and one I don’t want to let go for pennies but looking for a sensible price.

Thanks
