identification please, DCM mark

I found this pot today while rummaging through some Victorian pieces in a shed and wonder if any one can identify the potter , it had  a hand written label saying lond 80 which i take to mean 1980

Agreed, likely to be 1980, and Lond could be London. An incised monogram in place of a stamp points to a student piece. From the photos there’s possibly some bloating on the surface. Taken together it points to a hobby potter, possibly from one of the potting cooperatives based in London. Nicely decorated; maybe based on a group of skyscrapers in London.
