As a basis he was in a friends model shop and in the railway section spotted
some model or another that seemed to fit the bill but he wanted it done in wood.
Said friend called me and laid it firmly in my lap...

I got him back sometime later...

So I go tearing up to the shop and lo and behold there is said friend and fella and bridge kit.
Build a copy, wood only, Today tuesday, birthday Friday, can you do it?

Gritted teeth, did best suck in of breath between teeth,
made a few mental calculations and said yeah.
in all honesty not that hard but may be pushed for time with lacquer drying.
