yeah, i've never seen them. i didn't know that 38cm was an option. i have them in 40cm. EAI's site only seems to have them listed in 42cm. the QBP catalogs that I've seen online tend to only show 42cm as well. i got my 40cm set from yojimbos. you might want to call either him or john at businesscycles to see if they can order them.
