I imagine it looks something like this:
In that case, You're in luck old chap
(same rifle as the Diana Original model 25, made in germany with just a different brand name for export markets)
George Carl Donheim
i've got a Model 11 .25 ACP. paperweight. very poor quality. '60ish
It's a saturday night special. Got a barrel thats blue and cold. Aint no good for nothin ...
it has a broken magazine. the mag cost more than the gun is worth.
i'm not sure if gecado ever actually made any firearms or was just an exporter.
As far as I know it was import/export only - the rifle in question was definitely manufactured by Diana in Germany, and the Gecado name wasn't the only one it was sold under - The same rifle was also sold as the Geco/Diana/Original/RWS model 25 as well as the Winchester 425 and Hy-score 801
i imagine the quality was all different depending on the manufacturer. thank god technology has come a long ways.
Hey guys im off on an unexpected weekend away with the rents, as so i will not be able to post pics until Monday. It looks very similar to the one in the pic. I pulled her down today and re-oiled the old leather piston and made a new back plate. She is grouping at about 1 inch at 15 feet.
I have found some fractures in the stock that need repair, any ideas.
I am going to use it this weekend after so i will be pulling it apart to start the refurbishment. Needs a new spring ( cocks at 16.5 pounds ) and also some kind of front sight. Also might need some polishing to the sear.
Any ideas to increase the power?
Thanks for the support

When you fill your car with refined oil remember that it has been paid for with blood and guts, some from your own countrymen, most not.
Oil in piston tube = bad! She must be smoking like hell, poor thing. moly grease, you know it makes sense
epoxy and a clamp
You can order the spring and the front sight from here. As to increasing the power, you can always put a few washers behind the spring and maybe bore out the transfer port but I recommend you keep it standard - keep it for the sentimental value shooting sweetly and smoothly, and keep the spudguns for power
@ JSR, how would one go about removing the spring from a air rifle similar to the one in the pic in this thread?
my air rifle seem to be lacking power these days and i would like to replace the seal and spring one of these days.
Have a look at the breech seal too.
Changing the spring is a little tricky as they usually have an amount of preload, so the breech block needs to be supported with some sort of clamp in order to hold the tension while the retaining pins or bolts are removed, after which the clamp can be undone slowly, with the reverse being done to recompress the new spring.
I recently had to change the spring on my HW45 after it snapped, since the compression tube is relatively small I was able to do this with a 12" G clamp.
A rifle tends to be bigger though and may require you to make your own spring compressor, which is easily made using basic tools - there are various ways to go about this, have a look here, here and here.
ok ok, yep thanks for that i could ( if i put some time towards it) make one of those spring compressors.
the only thing i am becoming stuck on is when i get a clamp or compressor, and start to compress the spring, what actually goes down inside the cylinder and makes contact with the spring? do i need somthing else? there is a pin that i believe the spring rests on, and i know i need to knock that out, so basically do i need something that fits around the pin and pushes the spring back?
thanks much, dont strain yourself on this one btw as i cant do any of it as of yet (not at home)
JSR, is that a Weihrauch?
CO2 tank hybrid: Gotta fix the meter
Cane gun: Needs a pilot/fill setup
1.5" piston valve gun: Almost done
It depends on the individual model of airgun. In the case of the HW45, the pin goes through the round plug visible next to the compression tube in the first two photos (part ECP041 in this diagram) which is the part supporting the spring. Can you tell me exactly what model your rifle is, I might be able to dig up a how-to on stripping it down.
Yes, my first airgun and I love it to bits
ok well i dont have much time but this is what i found on the gun:
Cal 4.5 (.117)
Made in Spain
thats about it anyhoo thnx for the help JSR
Ah, a Gamo. Don't bother with servicing, sell it and buy a proper German/British springer
If this is your rifle, you'd have to support the endcap (ECP002) and tap out the drift pin DP002. Contact your local dealer, he should stock spare springs and seals.
selling and buying is kinda out of the question....
i might talk to my dad about it and he could get somthing machined up at work or something.
lack of tools is not really a bother my dad has been a boilermaker/engineer for nearly 26 years, its just a matter of time before he brings all his tools home
thanks much JSR
that helped alot
