Lee Enfield No.4 magazine colour ?

[Donkin]

Hi all, picked up some magazines from FOC recently, and I’ve never before see these mags with a greenish parkarised finish, anyone have some background on these, both marked F with broad arrow

Normal for post-war replacement mags. Oil and them and they’ll darken considerably.

The Brit’s would suncorite over the park often, but good luck finding suncorite in Canada today.
