My searching has produced two possible ID’s as:
(i) 5mm French Revolver
(ii) 7mm Perrin
However; neither seems to fit the descriptions very well.
Is it possible that these were produced by a competitor as similar but; not identical calibres?
(i)
(ii)
The dimensions of the two cartridges, in mm, are:
(i)
Case: 12.65
Rim: 7.00
Base: 6.05
Bullet: 5.06
OAL: 18.30
(ii)
Case: 13.85
Rim: 9.05
Base: 7.80
Bullet: 7.40
OAL: 21.60
Any help in identification would be greatly appreciated.
