Any Electricians Out There?

Hey guys, I need some help here. I am trying to find replacement lamp cords for my 70's lamps. However, the only cords I am aware of use huge, bulky cords and plugs. The cords and plugs that are original to the lamp are thin, both the cord and the plug. I would like to find out where to get replacements as I shocked myself while plugging one of these lamps back in. I guess age finally caught up with the cord. So to be safe, I am replacing all the cords on these older lamps. Don't need to burn the house down.

I have been reading and SPT-1 wire is much smaller (insulation) than SPT-2 (thicker insulation) - the wire on the right says it is SPT-2. Is the wire on the left SPT-1 or even thinner than that?

The wire on the LEFT is the older wire and plug I want to replace.

Here is a picture..
