I picked up this today:
Wargame Rules
Rules for Wargames in the 1880 Period Including Colonial Wars
by Donald F. Featherstone
(signed on the cover, digitally obfuscated)

It looks to have been "re-bound", having its original two staples pulled and replaced with four.

I see that Noble Knight has an entry for it, but none currently available.

Any idea at value? Similar to the other Featherstone items? (Say $30-50 in ideal circumstances?)
