stamp and font good?

[Tx-Z 302]

So   The round top 3? Vs flat top 3 and the unaligned vin??  Can you explain or is that one of the non discussed things on here for forgery issues?

Not discussed here. 

The stampings appear to be genuine.

For what it is worth, that depends on a lot of things.  You can try the TC site, they have a section on
"What's it worth?" 

See this link. You will have to register for that forum.
