Vintage Canon AE-1 Program SLR Camera w/ Canon 50mm buying Lens

Product Name: Vintage Canon AE-1 Program SLR Camera w/ Canon 50mm buying Lens
This listing is for a nice vintage Canon AE-1 Program and buying 5mm lens. This is a recent estate sale find and it looks to be in good condition for it's age. Not being super knowledgeable about cameras, I was initially just going to sell this as I found it. After looking at it a bit more though, I've started to become fascinated by the work and design that went into this thing! I went and purchased the correct size battery and I now know that it seems to be fully operational. The led display in the viewfinder works. All shutter speeds adjust and function fine. Their was a bit of shutter squeal, but I have since lubricated this and it works as it should now. The battery door looks like it may have been fixed at some point, but it works as it shoul--I just wanted to notate that. I have not actually developed any film with it yet, so I cannot attest to anything up to that point. Please message me if you have any other questions and thanks for looking!.
