David,
I have Trigo adapters and rims, chromed.
Also have magnesium rims, Halibrand.
The Trigo pins were/are a pain. Mine are true now as tested at speed, so I dare not remove an adapter.
Terry Stapley here has just installed Vintage Wheels. They are very, very nice units. BTW, his pins seem perfect, no issues at all. Wheels went right on after he tightened them. Terry used anti-sieze liberally on everything.
On the Jag-based fronts, a person named Simon makes a replacement hub w pins to match the 5-pin wheels, eliminating the adapters altogether. In the image below, the Simon hub is on the left, on the right is the stock Jag hub w adapter (no pins shown).
The question came up if the Vintage and Trigo spinners had the same threads, so I tried Terry's Vintage spinners on my Trigo adapters. They fit the same it appears, threaded right on by hand.
Test of spinner threads.
Here is a Trigo spinner on a Trigo adapter:
Here are both spinners, Gold is Trigo, Polished is Vintage:
Here is the Vintage spinner on the Trigo adapter:
So,
from what I can tell, the wheels and spinners are interchangeable.
More testing can be done if it would "help the cause".
