It's hard to imagine a 28 on this frame, but I guess it's possible. Here are the measured dims. Sorry for the fractions but I couldn't put my hands on my dial caliper.
Across the flats 1 5/16"
Across breech balls 1 3/4"
Between f. pins 7/8" CTC
Interesting note, the fore end lug is one piece 4 3/16" long. Should be very strong.

You are correct Stan. PALUNC and others are wrong.
Dickinson DOES NOT use THE SAME FRAME for multiple gauges, they do not double up like CZ/Huglu and others.....
The Dickinson is a trigger plate action and easy to work on with excellent internal quality parts, many stainless and all are either polished or stone tumbled and deburred.
Internal adjustments are easy.Look at the internals of a CZ/Huglu and then look at the internals of a Dickinson....they are worlds apart in quality.
