Fish carburetor

I’m told that this is a Fish M-1 carburetor for a Flathead Ford V-8. I inherited it from my Dad, and it’s sat in a box untouched for 25 years. I haven’t done anything to it. Some men have been kind enough to identify it, because I know nothing about it, except that my Dad loved cars. I have read about scammers, and I was just recently scammed, but my cousin told me about this website, so I thought that I’d post this for sale. I’m giving the money to my mom who just recently spent a lot on my mentally ill brother’s teeth. I’m explaining this, so you know that this is legit. No offense, but I’m just posting to sell this, as I have no interest in cars. I’d like to get about $300 for it, and I’ll pay for the shipping. Thank you.
