14/2 NM compatible with 20 amp circuit?

[sixexx6]

Trying to install a flood light, when I identified the breaker it is a 20 amp. Looks like it has been one of the couple that has been replaced before. I'm using existing 14/2 romex which makes me question if the breaker is correct. (I thought that generally 14g goes with 15 amp) It is an old panel, probably 1988 with no identification labels except one small yellow sticker that says UL class CTR wich is not much information. If it is not a compatible breaker, what can I use instead and is there a way to tell what kind of panel this is without any labels? Most the breakers in the panel are BRYANT BRD BD, the one in question is CURTIS HAMMER BRD & A.
