Diana 45 Original love

The old gun still has it...IF you figure out how she likes to be held! I'm sure anyone who has owned one can attest that the old 45's can be hold sensitive, jumpy and noisy. I had disassembled this one, cleaned and lubricated after I got it a few years ago. The original leather piston seal was in great shape, so I left it alone. It sure is well built and can lay down some lead. 

This one is .177. I sure would like to try one in .22. I missed one on an auction a couple years back and kick myself. 

Anyone else still shooting the old 45?

I picked one up back in the late 80s early 90s at a gun shop. Made in the late 80s it has the later synthetic seal and shoots tiny groups out to 50 yards last I shot it. I really loved the gun and shot it allot back in the day. It seemed to take a liking to the Beeman Silver Bear pellets that nothing else would shoot. It was my first scope killer and I lost many a scope to this thing. Lost a couple to my 52 as well. Found that the cheap lightweight scopes lasted longer than the better scopes. I have had a Bullseye scope mount waiting to go on it for a couple of years and now that it is out I put it on with a better scope as well. It is very much neglected as I have a 54 that gets all of the attention when I want to shoot a springer these days.


 
Lovely rifles. Mine came from Gerry and Carol Thomas at World Class Airguns. For an extra 20 bucks, Gerry would perform a relube tune before sending it out. I refinished it and then had it hand checkered (20 lpi)) by John Groenwold on the grip, forend., and in front of the trigger guard. It still wears its original, fixed 4X Bushnell scope and is fun to shoot and a great garden gun.

RWS advertised these rifles as being capable of 2" groups at 50 yards, which was pretty good for a utility springer 4

0 years ago. Mine in .22 will do half that on a very good day - if I hold my mouth right!
 
Dig that checkering! And .22 to boot. 

When I took mine down to lubricate, I was taken by the work put into the gun. There was no de-burring to be done. The trigger is manufactured like a little machine with its precisely manufactured components designed to do its job for hundreds of thousands of cycles. I also appreciate the quick/positive lock up upon cocking. It reminds me of my HW95. DEEP bluing. 

This isn't my first gun, but it stirred something in me. 
 
You guys have some NICE 45's! Love the checkered one, and may I say World Class was GREAT folks to deal with.

History wise - in the late 1970's Diana's most powerful sporter was the old model 35, about a 700 FPS gun in .177. The 800+ FPS model 45 is based on a lengthened version of the 35's receiver tube, made to better complete with the "magnums" of the day, like the HW 35, FWB 124, Webley Vulcan, etc. The excellent but complex trigger in the 45 is completely different from the older Diana "ball sear" design, and AFAIK has nothing in common with any newer Diana designs. IIRC, the safety on the 45 had some issues, the original design getting changed pretty quickly.

The classic Diana model 50 tap-loading underlever was based on the model 35's power plant and trigger for many years. The model 45 served as the basis for the revised model "50 T01," which may be the hardest-shooting tap-loader ever made.

As mentioned above, the more recent model 45 is completely different - it's a model 34 action, in a stock designed to look like the older model (the tip-off is the first 45, and the 50 T01, have the stock through-bolt above the trigger).

Diana loves to confuse collectors by re-using model numbers, LOL...really the FIRST "model 45" was an underlever tap-loader made before WW2!

Just got a old 1985 original 45 the other day in. 20 caliber rare in the UK.
There great gun's really well made a pig to work on though.
I replaced the original spring with a Titan xs mainspring along with a good clean and regrease so smooth now no more of that horrible twang vibration that Diana's a and Originals always have.
Have too say along with the Wheirauch hw77 one of the best airguns when properly tweaked love em.

I got this one about a year ago from a member here on the forum. It was made in 1984. It had a cracked stock. I repaired that. It shot ok. But not as good as I’d hope. I just dug it out of the back of the closet today. Tore it all down. And ordered a new piston seal and a Vortek spring kit. I’m keeping it at the 12 foot pound range. I enjoy an easy shooting air rifle.
This will be my first rebuild. I’m excited.
