Purchased these monsters over the winter and finally got caught up around the house to make the internals; an unusual chest here in the USA. Many thanks to whom ever posted the pic's of the internals with a ruler as I was able to make/fudge two sets out as I only had the original bottom pieces for one chest (thanks for the extra scrap wood Mike!). Not museum quality but was not trying either. One chest was upgraded to a No. 3 Mk 2, but without the internals I have no clue what it was modified for, anyone?? After completion had to fill them, to check the fit.......
