First off there are a lot of people on this forum that can better answer your question than I. But to get things started The Blue Book of Airguns states that the Hy Score 55 was made by Weihrauch using B.S.F tooling and the value in 90% condition is $125. B.S.F. [Bayerische Sportwaffenfabrik] manufactured some nice air rifles under their own name and the Wischo, Bavaria,brands.I've always felt that the Blue Book value does not always reflect the market value of certain airguns, as such your Marksman 55 may be worth somewhat more depending on condition [a few pictures always help].The pricing on auctions have a larger spread in pricing than in a traditional seller-buyer situation.
Sometimes silence is golden,sometimes it's not.
