https://buinger.com/Feinwerkbau-Air-cylinder-for-air-rifle so there is a lot of value in the package but selling it as a package could be a big mistake and the reason why it will fit very few peoples needs
https://buinger.com/Feinwerkbau-air-rifle-model-P75-summer-biathlon so the rifle 2500.00-2700.00
mags 100.00 per
cylinder 140.00-170.00
compressor 500.00-600.00
this is a wild guess with no other than watching air guns for 15 years
if the price is too close to retail who cares but if the price is too good to pass up not matter what
all prices i found are on a quick search and i'm not doing more than that
also, this is a rifle that has a strict purpose and as such is a tool more then a look what i got rifle
and this would be a place to go for more info

all i have to give
good luck and sorry to hear of your friends passing i'm guessing
