After further research I've come to the conclusion that all of the 5 shot 38 specials seem to be in the "85" series.
I can't determine a designator for the high polish Stainless Steel in the few other models that they show with that finish.
Here's my guess. 85SS3 Series 85, Stainless Steel, 3 inch bbl
When I entered 85SS3 in the search box, I get a "Discontinued" page with no picture. http://www.taurususa.com/gun-search.cfm
.......And the mystery continues. hehe
