PARKER thrift time pen set and MOORE SERVO pen with details of nib and barrel imprint.

Parker thrift time pen set made with the same nice  plastic of the Moore Servo pen . Both pens are very hard to find in good condition. I was lucky!!!! 

Only once I saw a Moore  pen with this plastic and only twice , the identical  Parker thrift time.It's an hard job to be a fountain pen collector!!!!!
