Hi James, I use a combination of 1/48 and 1/32 from Gaspatch on 1/32 models. Check reference photo's for the sizes needed. Also the ball n socket "Albatros" type can be used on other German A/C as well, again, check photo's. I buy them direct from Gaspatch in Greece, shipping to Rhode Island USA averages 10 days. Regards, Pete in RI
