need some air rifle help

[bjor13]

I purchased an older air rifle based on on a local air rifle repair shop saying they could service it and had access to parts/seals.... Now that he has it he says he can't work on it. Does anyone know a place that could support a crossman challenger 84 (its form the crossman custom shop in the mid 80's)

Thanks!
