Not tanwall, but I like Contis, which still look good. I caution against older Turbos. I have have three self destruct (the tire peeled away from the casing) after about 5km each.
This seems to be a recurring issue with NOS road tyres. I've raided the inventory of old rubber at my LBS a number of times and old tyres just seem to age in an instant once you begin using them. I've had turbos peel, Vittoria twin treads separate where the compounds meet, and a pair of lovely circa 1985 Avocet Fasgrips go from brand new to perished unrideable in the space of weeks, mostly while hanging up in a basement.
Veloflex are probably the best racy option, and being available in a 20 is a plus for 80s and 90s bikes too IMO.
