Hello,
Thank you for the list. There is a partial set on ebay for $23.95, free shipping. It has some of the attachments you need. It had the curved wand, utility air nozzle, crevice tool, medium floor head with brush, upholstery brush, massage cup and blower tool. Most of them were duplicates.
There is another listing that I found, it has a lot. They are $18.99, shipping not included. It includes some parts for a Classic III as well. There was a Handi-Butler and a hose and Shag-Kings. A lot of stuff in general. Another listing has a handle and shoulder strap for $16.95 and free shipping. I have an extra Suds-O-Gun cap from when I bought my Shag-King. If you want it let me know. The only thing about it that is less than ideal is the screen. It has been replaced with a red one. The body of the part is blue but the screen is red.
Thanks,
Sean
