Missouri Area Tuneup and Repair

Hello
I am a in the closet air gunner. I am coming out. I bought from a coworker over 20 years ago a Beeman FEINWERKBAU-Sport 124 in 177 cal. I think it needs seals but I am not sure and want to take it, rather than send it to a shop that is trustworthy within 4 hrs of St. Louis, MO Does anyone have a recommendation. Thank you. Back years ago when I first got this rifle it was much fun and nice to shot at home. It looks like the price has stayed up, but I am not looking to sell only to have this fine rifle get a needed tuneup.
Thanks

Doesn't sound like what your wanting but my dad has a 124 delux in .177 and I ordered the seals and spring and he replaced them himself. I think that's one of the best break barrel hunting guns ever made. Target shooting would go to the 300s, but if you haven't shot a pcp and try one out you'll leave those spring guns in the safe for long long time.
