    Why not just tune a HW35 which is already a de-stroked 80 ?

    Am I missing something ?

    Hw35

    I agree why destroke an 80 when a 35 would do the same job. Perhaps it was fashion or people did not like manual barrel lock on the 35, or perhaps the 35 was seen as old hat!. Couldn't have been a power issue Venom were advertising 35's in various tunes up to 14.5ftlbs. They also listed a FT special 35 with reduced recoil and improved accuracy.

    The other trend from the 1980's I don't like was the chopping of barrels down to 14", OK on a std 80 or 35 but criminal on an Export.

    Hi Coburn

    The 35 will run at 12ftlbs quite happily with a shorter stroke so perhaps the one piece cocking arm of the 80 which supposedly gave a lighter cocking stroke was the answer.

    In my mind this is as near to the correct use of an 80 as you can get.

    A HW80 running at 21ftlbs being used to put meat on the table by some bloke.

    After all it's the power level they were designed to run at.

    Hi Mick

    I have this HW35e (22" barrel) that isn't marked as HW and no reference to Weihrauch or Mellrichstadt bay whatsoever but is simply marked as EUSTA in a horizontal diamond..
    The seial# is 620032 and produced in '76- Fergot to say- 13mm rails..

    I emailed Weihrauch for any info pertaining to the rifle but didn't receive a reply

    Nice Dog, whatever happened to that bloke?

    Looks like we've found out a lot on this thread. One thing I always wanted to know is at what point did HW change the delux/luxus stock on the 35 from the Bayern Cheekpiece version to the one with the Monte Carlo cheekpiece ala 80. It was some years before the 80 appeared. I've seen the M/C Luxus with serial numbers in the low/mid 700000's but I must admit to never seeing the earlier Bayern stock in the flesh.

    My theory on Rifles like yours badged Eusta, Hoffman and possibly Burgo as well, were made by HW for large German retailers who wished to use a propriety name to pass the products off as theirs.

    Many Originals were rebadged for sale in the States and Crosmans were rebadged for sale by the likes of Sears Roebuck.

    Its only my theory and could well be absolute c**p. Someone on here Garvin or Fraktor perhaps could offer more info?

    By the way thats a cracking 35E. The quality of HW's of the 70's and 80's is beyond question. I think the woodwork began to loose its quailty towards the end of the 80's.

    you know what, after reading this I think I need a 35e for the collection. If anyone has a nice one with open sights let me know, I may well purchase!

    I have never seen this Bayern luxury stock in the flesh. The DELUXstocks I have are the squarer front ended walnut ones which, to be truthful, aren't my favourites.

    Interesting thread this.

    But there's a bloke who looks like he could be his dad on page 76 of April's Airgun World.

    Nice one John

    It looks like that one is pre barrel pivot shims as well, same as my old girl.

    I bought the shims from John Knibbs then struggled like hell to get them in only to find out later on here that it shouldn't have them.

    Anyway seeing as this thread has become a HW35 show and tell here's mine

    http://i1138.photobucket.com/albums/...Picture007.jpg

    (sorry I only have one picture of it)

    After buying 2 early MK2 HW77ks and an Airsporter S off a mate of mine for £90 the 3 in 1986, he vanished into the coal shed and came back out with this 35 and gave it to me for free.

    It's cost me a small fortune since then in machining and workshop time, but who cares.

    After fixing the porous breach I decided to have a play with it.

    She's been stroked up to 71mm (standard 65mm) then de-stroked down to 52mm and the spring guide and top hat are made from stainless and I've had both factory piston head types fitted as well as a few brass and alloy heads but at the moment it has a Bowkett style twin O ring aluminium piston head.

    And I've not finished playing yet.



    All the best Mick

    Hw35

    Just been shooting my HW55 serial no 878*** which had a leather piston washer fitted so it would appear that whilst the 35 got the nylon washer at the same time as the intro of the 80. The 55 and I suspect the 50 as well continued with the leather washer.

    Until when is the next question we need to answer.

    Agreed Mick that fellow in AGW this month must be his dad.

    Hi Coburn

    I have a bit of a theory on that.

    Just as the HW35 changed to a nylon seal with the introduction of the HW80, could it be that the 25mm cylinder Weihrauch guns changed from leather to Nylon seals with the introduction of the HW77 in january 1984 ?

    Though it would seem strange if Weihrauch did carry on producing leather seals at 25mm four years after the introduction of the 30mm Nylon seal.



    All the best Mick
