The Dianawerk / RWS target model 100 .177 cal was made between 1989-98. Its a very expensive rifle.
Yes Diana RWS rifles are still made. See the link below.
The Lincoln Jeffries air guns were the forerunners of the RWS airguns. They were manufactured from the late 1800's and into the 20's when they became RWS. Today the grandson makes the Marksman brand airgun pellets
The major air rifle manufacturers are Gamo, Crosman, Benjamin, UTG, Daisy, RWS, Beeman, Mendoza, King Arms, Hornady, Beeman, Air Arms, Air Venturi, etcetera.
I would use Crosman Pellgun oil. Or RWS air gun oil.
Any .177 cal pellet can be shot from you air rifle. However you will find that some brands are much better than others.
Go to ( See the link below ) and find your parts and owners manual for your gun or rifle. Crosman keeps a web page for older airguns.
