Hi Thomas,
If you click on the photo, it will increase in size one time. If you go to the lower, right hand corner of that larger photo, it will increase in size one more time...
It appears that the toggle parts are of a larger size/scale than on the luger pistols...the photo caption says this was a machine gun adapted to aircraft use...
Regards,
Pete... <img border="0" alt="[typing]" title="" src="graemlins/yltype.gif" />
