I would like to have one of these in my collection, too - mostly because being 3/4 size, it has the "cute" factor. ;)
But, it's also a great sewing machine with that perfect straight stitch. :)
Replacement parts are cheap and easy to find: I buy everything I need from shop.sew-classic.com or from a couple of eBay sellers.
There are free manuals for it on the web, but if you can't find one, p-mail me your email address and I will send you a pdf.
There's a ton of free info and instruction on the web about cleaning and maintaining these old machines - you don't ever have to pay a repairman for a clean, oil, adjust (COA) if you are interested in doing it yourself. Tools For Self-Reliance has about the best manual around for refurbing this machine and several others:

Have fun! It's a cutie! :)
