This is an interesting item!
its meant to be for 6mm wargaming...., but at 6 inches it could quite well feature in you 10mm or 12mm war gaming and theirfore also useful in the 1/144, 1/150 & 1/160 n-Gauge modeling
The price isnt too bad? £5.50 or @$10-12?
They also do a range of 15mm items to go with the 6mm item range, I think a number of these items would work well with 1/144.
The pipe works will work on a number of levels and as a lot of this stuff is "future Sci-fi" it modernist or brutalist in stlye...
A bunker or block house tends to look the same regardless of age!?
Obviously you "Gundam" or "Robot" fans may even wish to stretch to some of the 25mm range!?
