Blurry 'ell! I just had a read through that PDF. While aware that some people do work with brass etches and such, I had no idea how complex such kits and builds are. Reading that was an eye opener.
Any one of you who work to this level have my respect and admiration without limits or reservation.
I don't believe that my aging eyeballs would let me work to the required level of detail unfortunately but it's great to know that some can and do.
Thanks to the OP for the opportunity to be 'WOW'ed'.....
