Head spacing with only a FIELD gauge.

[USGI]

Ok. My Forster Field does measure that 1.299.
The No-Go is 1.297 and the Go is 1.291.

Ten, are they also stamped with those same numbers? I guess mine are older than I thought - without pulling them out, I remember them as 1.290, 1.296, and 1.302. - Bob

EDIT: Correction - My field gauge is stamped 1.299 - not 1.302.
