I was looking through The Blue Book of Airguns and noticed a Diana model 20 which was 20" loa. Have you ever seen one of these? I would like to find one for my grandson.

hasn't been made in 80 years, since before WW1. The model 20 thats currently available is much larger and is an adult airgun. If you are looking for a small air rifle, look for something like a Diana model 16 or model 22. Watch the auction sites, variants of these appera regularly under the Hyscore(models 806 and 806) and Winchester (models 416 and 422) name.

thanks for your response. Keep an eye out for the old one.

you may take a look at it on the Diana catalog http://www.diana-airguns.de/DIANA_Catalogue.pdf

If you or anybody else know of a USA dealer who's carrying this gun, please let me know, I would like to buy one for my 8 year son.

I didn't see your response before my previous answer to the original question on this thread. Thanks for the info!
