MB 234 1/2

[guyy]

I had been looking for a 4 sized vintage MB because although i like the nib on my 1950s 146G, i begin to notice its weight when i'm writing with it for an extended time. I ended up with a 234 1/2 which seems to be a popular vintage MB. I think this is a fifties version, with the gold nib and what i think is a non-telescoping piston. (I haven't opened it up) It's marked "234 1/2" and "BB" on the blind cap.
