Hi .. I am wondering on the expression of " Sovereign" being attached to some Sheaffer Pens.. Can someone enlighten me why and when the pen is called " Sovereign" ..or is it a brand name like 51 and 61 in parkers.. I have seen Plastic sheaffers and called Sovereins and seen also some Imperial silvers also named as " Sovereign" .. what is this all about? what are the measures??

In the case of Thin Model Pens, the Sovereign could be one of two trim models:

Sovereign TM (Early) - The Sovereign TM is essentially the same pen as the Statesman, but without the White Dot and fitted with a Feathertouch type nib. The two pens could easily be confused with a cap swap, and sometimes the pen may be found with the other model pencil.
Identification guide and features:
Conventional 14 karat gold two-tone platinum masked nib, stamped "SHEAFFER'S" over "Feathertouch" and hallmarked - Nib is Sheaffer nib code 73
Some models will have conventional 14 karat gold two-tone platinum masked nib, stamped "SHEAFFER'S" over patent information stamping and hallmarked - Nib is Sheaffer nib code 74
Nib grades included extra fine, fine, medium, broad, and shorthand
Visulated section
Gold filled innerspring clip
1/4 inch wide gold filled cap band
Plastic cap and barrel in solid colors
About 5 1/4 inches long capped and 6 1/8 inches posted
Available colors were Black, Burgundy, Evergreen Green, Persian Blue, and Burnt Umber Brown
Retail price for the pen was US $8.75, matching slip-cap ballpoint US $6.00 (Late 1951), and matching pencil US $5.00

Sovereign TM (Late) - The metal cap Sovereign TM is similar to the Statesman, but with a stainless steel cap with a White Dot and fitted with a Feathertouch type nib. This version of the Sovereign was probably manufactured only in 1951, right before the Snorkel was released.
