Actually, I should know better, there are buttonholers that will work on slant shank machines and do have a feed dog cover plate. I just got a buttonholer for Touch & Sews the other day. The ones for the the slant shank machines are longer than that.one. I'll have to look at the ones I have for the regular slant shanks like the 301, 401, 503, etc. A good picture of various plate for the buttonholer can be found at

I've had trouble getting screws in feed dog cover plates like that one so if you have any tips, please let me know. I have enough buttonholers that if I can't get the screw in, I have plenty of others that I can borrow from.
