New to allotment holding

Hi All, Albeit I have always had an healthy interest in backyard gardening having taken early retirement 18 months ago I have taken an allotment in south Lincolnshire.
I have a question which one of you maybe able to help with regarding identifying the variety of seed potatoes a fellow allotment holder gave me today, 3.5KG of small seed potatoes ( oval 1.5" long smooth skin )stating that they were salad potatoes and needed to be planted about 3" deep and 6"apart for cropping in August
 Any ideas would be helpful.

hi abbeyview and welcome to the site - unfortunately there are lots of salad pots and they most of them look the same  - but at an educated guess i would say charlotte - as that is a smoothed skinned variety and also a very popular one too.

  Got a cough DD!

Guys, many thanks for the quick replies, second question should I plant as suggested 3" deep and 6" apart or as I normally would earlies 5" deep and 9" apart.

ive put mine at around 5 inches deep and around 10 inches apart

You might find you don't have much soil for earthing up later on Matt.... time will tell 

i know but i had loads of seed potatoes and very little space - also the space they are in i wans't going to grow much in anyway - but like you said time will tell - oh and by the way im hoping to earth them up with grass cuttings.
