.. i'm trying to learn abt transmissions too ..
I know just a little more than the basics.
your syncros look pretty good , the points are nicely shaped and even and i don't see a lot of burrs on anything.
The rings look to be pretty round too , not flat ( flat = not good )
And i think the "dog teeth" are the ones that are actually on the gears .. those look nice shape too.
Seems like a lot of marks on the gears themselves .. not sure how that happens .. worth mentioning though.
From my "laymans" point of view .. the syncros and rings look a little "too good" .. like they have been serviced or replaced .. again .. not an expert .. just making observations based on what little i know.
Sorry i can't be of more help ..
Thanks for posting more pics
and .. how do you like Flickr ?
I like it a lot on the computer ..
links & scaling mess on on mobile phones
when you copy a link it actually give you the photo "next" to the one you intend to post
and you cant get a slideshow on mobile .. ( argh )
but it's great on the computer.
