Hello Les
I am sorry I did not see this post till today. I assume you went to see the saw from your post.
Here is what I could tell you being a RBI scroll saw owner. This was one of their earlier saws and do not make them any more. It is built on the 220 platform. From the photos it looks like any Hawk saw but shorter bed. The key things to look for are the motor. Does it start and stop. I am not sure if this is a VS model or not. I can not see the other side of the motor. If it is make sure it goes through its speed changes.
Next is the bellow. Being an older one make sure it is not dry rotted and it supplies air to the air hose.
Make sure you have at least 2 of the blade holders. These are different from todays holders so not sure how available they are. Make sure the table tilts.
The bad thing with this saw is it does not have a quick blade release up front. That means you have to tighten and loosen the blade from the rear and that becomes a pain in the butt if doing alot of pierce work where you have to continually thread a blade. Also if not VS speed I would stay away from it. 14" saw is way too small for me. You can do better for $300. You can find Dewalt 788 on Craigs list for that and they are a 20" saw with all the features.
Other than that it can cut wood.
