/diy/ - Do It Yourself

Looks to be a 315 model. That was the Diehl Mfg Co. They got bought by Ryobi in 1988. You saw is from the mid-'60s.

1) Pretty sure you have measured that incorrectly. 5/8ths and 1/2 were pretty standard back in the day but I've not heard of 3/8th. Picture related. Place not the saw they use as an example.

2) That is indeed a 7 inch saw but it will take a 6 and a half blade if you can't find a 7. They do still make them but you'd probably have to find them online.
