Part of our "6 Posts in a Day Tour" Myself and BK alighted at this post hoping it was open? But alas still locked on two padlocks similar to KE's report of 2008. So surface pics only.
Located within its own compound, very overgrown but still all intact

The post sits in a corner of the field, just off a footpath.

The compound is very overgrown with stinging nettles, the entrance into the compound is barred by one of the posts, sprung bed frames!

Trampled down the undergrowth with my size 11 boot to get some good pics!

The air vents are made of aluminium, so are still in a nice condition

Thanks for looking!
