Alberto,
The gear ring as you say, what model is the one shown from? It looks to have very strange dimensions, as in the inside hole looks very large. 116 maybe?

 

Vince, good to hear from you! It is from a CR set, found it at a friend's here. He does not need it, so I am replacing consumables.
Synchros, sleeves, bearings, etc. The 'gear rings are not in any catalogue of the usual suspects.

The top photo, they are in reality dog rings, different from a regular street box

 

You can see them on top of the 4 gears ( photo: Centerline)

 

Alberto. Your photo does not show Alfa dog rings. They are something else. Look at the photo of the dog rings from Centerline. The gear set you pictured uses standard Alfa type dog rings, but they're made by Bacci.

If you need synchros, use Goetze. If you are not able to buy easily from a vendor I can sell you some. I also have NOS Alfa moly coating rings. Please post the dimensions of the synchro rings though - to make sure they are the same.

 

Thank you Rob!

I am very confused, as the 'dog rings' came off a CR set. Made by whom, I ignore.

I definitely require the synchro rings, yet I am traveling today to Europe, will be in Bologna for the Auto Classica, and will take the samples with me.
I will keep you updated. Can you DM your phone number and I will call you today, before my 7PM flight.

Thank you!
Best,
Alberto

 

Alberto - sent you a PM. Safe travels and enjoy that wonderful city.
