Yes Diana RWS rifles are still made. See the link below.
Not much. They both make inexpensive to very expensive air rifles.
There is a problem with identifying the dates of Diana air rifles. Diana made air rifles in Germany before WWII, during the war the Germans made them switch to firearms for the German army. After the war the Allies broke up the Diana plant and sold off all the machinery. Some went to the Millard Brothers in Scotland and became "Milbro". Later Diana finally got he rights to the Diana name but had to make air guns & rifles for other air gun companies. Today Diana is back making their own air guns and rifles. You can try and contact Diana to see if they can help you. See the link below . Remember to switch the page to English. You will find the English tab at the upper right when the page opens
I believe your air gun was made by Diana. Who made air rifles for HY-Score. I think it's a Diana model 23. If so then it's worth between $45-$60 in good condition.
No; their ammunition is too big and dangerous to be shot at people. Only airsoft guns are allowed in airsoft.
Okay. I'm going to try to keep this simple because there are volumes written about Diana. I'll start with RWS, they are a division of RUAG AmmoTec GmbH of Germany.Now for Diana: Diana's real name is Dianawerk GmbH & CO. KG, Mayer & Grammelspacher. The name Diana appears on their rifles and has become synonymous with their guns. Diana has been making air gun since before WWII. During WWII the Nazi's forced Diana to produce Mauser's for the Germans. After the war everything was sold off or destroyed. Milbro of England bought the major machinery and made Milbro air rifles in Scotland some were called Diana. When Diana finally got started up again They started to make rifles for other manufactures. This is where you see RWS and Diana crossovers. Diana also made rifles for Beeman and Winchester. It's not uncommon for air gun manufactures to make models for other companies. The Daisy model 130 is also known as the EL GAMO.
Diana makes Original Air RIFLES.
Atticus gives Jem a box with a single gun inside, and he gives Scout a fishing pole.
