Spring/Piston Model 52 Broken Spring

[TAPnAR]

I dug out my old RWS Model 52. Tried firing a few shots through it and I noticed weird Chrono numbers.
I decided to take it apart and see what was up. I noticed the spring was broken into 3 pieces. The gun has less than 500 pellets through it.
I checked the piston seal and all seems good there.
Is this a common issue with Spring piston guns?

Thanks,
Todd

Thats part of the reason many shoot aa guns. Easier to change the spring

I don't think it is going to be an issue getting it back together. I just need to find a new Spring and spring guide.

If you haven't, I would try Hector Medina Connecticut Custom Airguns

I don't know what vintage you heard about but my 48 was made in March of 1987 and when I installed a vortec spring kit the original spring was in good shape after 30 years of shooting it.
Only reason I did that is to try and recover the lost power from moving to a higher altitude home.

I remember when I first purchased a Vintage Winchester 435 (Diana 35), the cocking stroke could only be classified as "crunchy." Then all of a sudden, it smoothed out, but it shoots a only about 500 fps or so. So I asked the folks on Mr. Gaylord's blog, and they told me all about Diana's brittle springs that would break and then wind into each other. Someday, I will have to peek inside. But I can only disassemble one ball bearing trigger gun at a time, and the 24D is currently apart.

Thanks you for all of the info and suggestions. I have the parts ordered, and will have it back together soon.

Mine is around 1996 vintage. but it has spent most of it's life in a hard case.
