Likethedog,
If your Wizard is like the one I have and uses low shank feet and attachments, there is almost an endless supply of them.
Sew-Classic {
http://www.shop.sew-classic.com/ } has many different feet and you can find button hollers and other accessories occasionally on Shopgoodwill.com {
http://shopgoodwill.com/ }, your LSMG and eBay.
Without pics I couldn't even begin to guess when yours was made. I'm not even sure of mine, mid to late 60s I think.
