This unit holds the pocket clip to the top of the cap on both Aerometric and Vacumatic Parker '51' models.
Very often these are either missing or damaged.
These Light Grey / Pearl coloured Jewels are 100% original and are offered with the brass bushing as a complete unit.
This Jewel type and fitting unit is for the Parker "51" cap only.
Fits Parker "51" Caps on models from the early 1940's up the 1960's.
Please note that due to slight difference in the threads of the Jewels, we only sell the Jewel with the correct threaded Bushing Screw.
We do not sell the Jewels separately.
