Had some freetime this afternoon and decided to see what I can see on my Falke Model 70. I must say internally it is vastly different than any Diana model 27. Appearance wise it does look more like a pre-war Haneal Model III, not sure about internal but I am guessing they would be very similar as well.
This is a go as slow as possible, document, learn and share as there is no detailed information related to disassembly of this model. Disassembly of the air rifle is very easy, a very thoughtful concept for the time.
Here is what I have found/learned so far:
1. No pre load, the main spring is very short only 7.5 inches long. The measurement from the spring guide base to the top of piston is only 8.38 inches in its resting state. The actual length of the spring was a real surprise, my only comparison is it seems as though someone cut an FWB 124 spring in half.
2. The leather piston seal is still in place and appears useable so I soak it in neatsfoot oil and will leave as is for now.
Not sure if the blind pin holds the piston seal screw in place, another reason to leave piston seal alone. If I ever feel the need to replace the seal it is a 1.1 leather seal and 28mm in a synthetic conversion. I am also hoping one of our neighbors where this model is more prevelant would be able to provide some guidance on the piston seal screw removal.
3. The breech seal is leather and fairly flat, may need to find a replacement or make a new one with my hollow punch set.
4. Will need to find shims for the barrel pivot as there is just an ever so slight movement. I think the shim is a better option verses grinding another small notch in the pivot screw head, which would work because the wiggle goes away with an additional 1/8 turn of the screw.
5. The barrel lock up mechanism is very simplistic, but a feature I really like.
6. The trigger is in a block assembly that unscrews from the compression tube. This was a surprise and until today the only air rifle I ever unscrewed the trigger housing on was my Beeman R1 or Weihrauch HW55 MM. I will not be playing with the trigger as I like how it is set.
7. The spring guide is part of the trigger block assembly. Another surprise, I had only seen a similar design used in FWB 124.
8. I have inspected the stock and have decided just clean it up for now. However, it does appear to have some of the worst clear coat finish I have ever seen. The only finish on an air rifle stock that may be worse, would be one of the various Chinese B3’s.
9. The blueing is in fairly good condition so I will be leaving that as is. In addition, there is really no significant rust worth mentioning or worrying about and what is there should been resolved by light use of 0000 steel wool.
That about covers it for now.
