I have read v coerulea is much more vigorous than the other varieties. I got a C. walkeriana v coerulea seedling from Sunset Valley Orchids in December in a 2.5" / 6.3cm pot, SVO5365. I was surprised by how many pseudobulbs it had. Right now it has begun 7 new growths, and I think it might make even more.
It looks very strong. Hope it will give you flowers soon.
Thanks for the generous offer! However I am in Canada . I did order a 3 growth walkeriana flamea 'Tonkutsu'. Hopefully it will be as vigorous as yours!
