Lee Enfield No. 4 Mk I - Seeking Info

[browningautorifle]

Hopefully the $800 I spent in total on this and the SMLE No. 1 Mk III* puts me somewhere in the ballpark of a reasonable purchase.

I would say so.

Does anybody have any leads on some gauges?

If you type "303 headspace gauges for sale in USA" in your search engine you get no shortage of sources. Also a WTB in the correct forum in this site may glean you a set.
