The Parker 61/65 Cloud Series was introduced in 1975 with the Cirrus, it was followed a year later by the Cumulus and Stratus, all the patterns being based on cloud formations. They were very popular but sold at the high end of the market and now they are quite rare and command premium prices compared to standard 61's or 65's.
This is the 61 Cumulus dating from around 1976, It is in very good condition with only minor marks. The plating to the cap and barrel is in excellent condition. There are some minor marks on the grey shell where the cap has been removed and replaced.
