Skil model 67 blades?

[hertfordnc]

I crawled under the bench at my favorite scrap yard and pulled out a Skil model 77 not sure the age and a model 67.

THe 67 is really interesting, small, light, powerful, I could see it getting a lot of use if i can find blades for it.

I guess the original blade was 5 5/8"

I can't find anything even close with a diamond arbor.

Any ideas? This saw is not pristine, I just plan to use it so maybe I could modify the arbor?

Or, possibly, cut out a diamond from a 5 1/2" blade?

Thanks

Ya thats not a common size to have a diamond knock out.
