M-2244 C.P. Co. marked unit on the right and a newly discovered, yet unlisted style on the left. This piece is also incuse marked C.P.Co. and while it shares the bottom shell from the M-2244, it has a much larger top shell.
Always looking for CP multiparts, if anyone has an M-2101 or M-3068 they are interested in parting with please let me know! (Could also do with a quality photo of an M-2101)
