1. The Forum Rules have undergone some minor changes and updates.  Please take the time to read them; it will only take a couple of minutes of your time. By doing so, you lessen the chance of incurring the wrath of the moderation team or making yourself look foolish to other members.

    90% of users posting adverts in the Sales forums need to be reminded to read the rules as their posts are wrong.  This is unnecessarily time-consuming and will no longer happen - if your advert doesn't follow the Sales Rules it will be deleted and you'll have to start all over again.

  3. Dear members,

    Our membership (like our country) consists of people from all walks of life; different in far more ways than can be listed here and each with a different view based on their experience of life - regardless of their colour, religion or cultural heritage. Every single person in the UK has been born of mixed race – we are a multi-coloured and multi-cultural country.

    As many of you are aware there are a handful of individuals amongst this membership that persist in making provocative, inflammatory, racist and otherwise offensive comments. This has been happening across the forum to a certain degree but is most especially prevalent in the Adult section.

    The moderation team has tried to stay on top of this, however unfortunately because of the ‘offensive’ nature of much of its content we don’t monitor the Adult section quite as much as perhaps we should. As a result much of this behaviour has gone unnoticed unless it has been reported to us. While the team always intended to take a "light touch" approach to the Adult section it would seem that some people aren’t quite adult enough to be left unmonitored after all.

    This behaviour is, and always has been against Forum Rules as well as the specific stipulations of the Adults forum and it will no longer be tolerated. We feel it's time to draw a line in the sand and as such from this point onward offenders will receive an immediate and permanent ban from the forum.

    In order for us to achieve our goal of restoring the forum to the friendly and tolerant place it once was, we ask that ALL members be mindful of the content they post and help us to stop unacceptable behaviour by using the 'Report' tool at the bottom of any offending post - the results of which can be seen only by Admin/Moderators.

    You should all receive a copy of this message by PM.

    an old mate of mine has just popped down for a cuppa and he's brought his old diana down with him as its devolped a bit of a twang when fired,basically once the triggers pulled and the cycle completed you can here the spring resignate for a second or too and its only started doing this recently,
    to me from firing it,it feels like theres no preload on the spring,but it doesnt sound or feel violent though,
    other than that the cycle is very smooth and soft,i dont know a lot about diana's so not sure if its been tuned at some point but it does feel a very nice and solid rifle to shoot
    unfortunatly i dont have a chrono here at the min so cant check power
    basically im just wondering can anyone give a bit of info on this rifle,namely age,approx value ect ect
    also any ideas on the twang is it something associated with dianas?
    heres the rifle anyway,its .177 diana mod 34 firebird,scope is a tasco 3-9x40 (siver antler im presuming) serial no. off rifle is in the pictures
    thanks

    I believe the 34 didn't have a spring sleve like the model 45 ,hence I guess won't help the twang.
    Rear guides weren't wonderful either slightly loose and tinny.
    the early trigger unit t01 are great in my opinion however their can be a fair bit of play between the trigger unit and main cylinder and although I wouldn't recommend you do it my old venom tuned 45 had the rear of the cylinder adjusted to provide no play .
    simple to strip and improve, don't over spring it these shoot in .22 best around 11 ft lbs and cocking effort can be heavy.
    Whip it apart ,ptfe sleve , either polish the steel guide or buy a new one , you may get away with the spring once polished ends and lubed.
    IDE doubt it's broken but you never know .
    These are great rifles ,and better tuned.
    Rear quality rifle your mates got.

    If you look on rear left side of cylinder it will say made in west Germany and give 4 didgets ref to date . Fire bird were early models I think possibly the first few years of release.
    They too did 52 firebirds I think possibly 87 but I'm not sure I have a mint one boxed away but can't get to it easily but yours will have date stamp.
    Value not sure really but not as much as the higher grade 36/38 model which were rarer I think .
    ide say less than a Simular 45 too .

    ide guess yours maybe 90 ish ?
