304 or 301 ink cartridges (Knaresborough HG5)

I’m trying to get a working printer I’ve got an old HP desk jet 2549 which uses 301s but am waiting for a power lead to arrive to see if it works and just bought a hp 2600 at a car boot sale 😬 which uses 304s. I Wondered if
Anyone had any cartridges going spare that I could try them with. Many thanks for looking.
Can collect.
