I’ve attached a scan for a 24″ scrollsaw, model EX-2, manufactured by J. Philip Humfrey International inc. by Sommerville Design & MFG inc., made in Canada. This was likely their first model, it was sold in 1984. This particular Excalibur scrollsaw has a tilting bed – later models would feature a fixed head and tilting saw.
