I haven't delved into their site much yet, but there's a new producer (Company? Single artist? Not sure on that.) of optional parts made specifically to fit Volks dolls. They go by the name "Erfolg Plus" (エアフォルクプラス. The sculptor seems to be focusing on making double-jointed arms for the Volks lines that are still single-jointed, but they've also got some high-heel feet and even a head. So far, they've made arms for YoSD and SD/SD13 girls, and according to their blog, they have finished prototypes for double-jointed SD13 boy arms. I decided to put this discussion thread in Larger Dolls, because only the YoSD arms are for small dolls - everything else they've made so far is for 1/3 scale. You can see their site here: http://www.eonet.ne.jp/~erfolg-plus/ (NOW DEFUNCT) And this is the shop on their site (to help the Japanese-challenged among us): http://erfolg.cart.fc2.com/ (STILL THERE as of 01/12/2010) And here is a link to their Y!JA auction listings: http://openuser.auctions.yahoo.co.jp/jp/user/tyoubakunyuu (STILL ACCURATE as of 01/12/2010) A link back to the News thread on this company/artist.
