Interested to find growers that grow, Thujopsis dolobrata 'Compacta' and / or 'Gracilis' and / or 'Latifolia'? Or have the whereabouts of a grower that may have availability?
Hi Frank ... over the decades, many of these "ancient cultivars" have been lost to cultivation for no particular reason. These days, the only commonly produced cultivars of this species are 'Nana', 'Aurea' and 'Variegata'.
If you really want the specific plants you're after, you should try to find one growing somewhere and ask for cuttings that you can propagate yourself.
Frank, Bruce Appeldoorn of Appeldoorn Landscape Nursery in Bostic NC grows/sells numerous cultivars of Thujopsis dolabrata. I’m not sure where you live, but that may be an option.
