You need to have created three posts before you're allowed to post a picture (it's an anti-spam feature), and there are detailed instructions in the FAQ topic, which is pinned in the Type Talk sub-forum. 

If it's a Brother, there should be a serial number plated riveted to the back of the machine, that will help to determine the year of manufacture. As for the model, a photo would really help as Brother made a seemingly endless number of different models. It sounds like an earlier model such as a JP1, but we'd need a photo to positively ID it. On most Brother machines the model name is on the front valence, but since yours doesn't seem to have it, I'd consider that another indicator that it's an early model.

Okay so the serial number on the back reads
H7688415

A simple photo of the front of the machine - or a link to one identical to it that you've found elsewhere - would give us the decade.

I'd say it's from 1967. Its case and overall design is identical to other Brother models I have from the era, but I don't know what this particular model was called. I've seen others like it, so it isn't uncommon; maybe someone more familiar with the brand can provide a more concise answer.
