FN Browning Pocket .25 auto?
 

I got this little pistol in trade for a Snapper 20" push mower a month ago. Not in the best of shape with maybe 10% blue left. But it is complete and original and OK mechanicaly. This is the type with a grip safty and appears identical to a Colt 1908 .25 auto. I think collectors also refer to this one as a 1906 FN Browning. I found a website with some info on these but the text won't download. Anyone know of a way to determine approx. year of manufacture for FN pocket autos?

Thanx, Stevie.
