3825 has been end-of-life since 2005. The firmware files are no longer available to the public.

for such old gear a google is ur friend; plus used gear on ebay; I would go for 7200 which is old as well but very cheap on ebay and only one from "old ones" that comes with IOS 15.0 and 15.1 the latest release. GNS used have 3825 and 7200s IOSes , check their forum as well

Hello @hs08
EoS of that platform, around euh..long time ago: EoL 2016.
So, IOS no more available on official website... 15.1(4) is the last IOS I know for that platform...
For lab environment ? I hope...
