There is. that is the first tyre we recommend. We list it on our 911 page as well http://www.longstonetyres.co.uk/page/porsche-911
One of the best options and certainly the most correct for early cars. the CA67 is currently the only pre 1965 tyre made in 165R15. then the XAS came out in 1965. then the Cinturato CN36 in 68.
Because of a request on another site i have made a short film about tubeless tyres and wheels https://www.youtube.com/watch?v=kWJ-tWP3iU0&t=58s it might be interesting.
However to summarize
if it says tube type on the tyre fit a tube.
If you have tube type wheels fit a tube.
if it is a 70% (eg 185/70VR15) or full profile (eg 165R15 or 165/80R15 (same tyre)) you can fit a tube, even if it is a tubeless tyre. (you can also fit tubes on tubeless wheels)
If in doubt fit a tube except if the tyre is 65% profile or lower (eg 195/65R15) do not fit a tube, do not fit 65% or lower tyres to a tubeless wheel.
