- Mitrailleur van 40 mm No. 4 dubbel (twin mounting)
- Mitrailleur van 40 mm No. 5

Thank you for these designations.

I assume you have seen the book on the 40mm by Terry Gander - "The Bofors Gun".

This is a link to the Kindle ebook: https://www.amazon.co.uk/Bofors-Gun-Terry-Gander-ebook/dp/B00QVZPR88

Ive heard about it and i think i even own it but i have no clue where it is as ive recently moved and i havent sorted out my book colletion. But to the paint i was gonna make, the book seems to have incorrections. For example the book says that Poland recieved some 40 mm L/43 submarine variants and that they even used some of them on a polish destroyer but in reality this never happened and the guns where sold elsewhere and some was forced into Swedish service. Since the book is really long its hard to point all incorrections so when using it as a source its better to look at all the data with a grain of salt.

Polish:
"40 mm armata przeciwlotnicza wz.36"
" -//- -//- wz.38" (gun carriage "Semi-stationary")

and bought in Sweden for ships two barrel types:
wz.36 [L/60] and L/43 for submarines.

export with ammo: (orders / without details)
to ES, 1938: 24 pcs wz.36 (official to Peru)
to UK, 1938: 80 pcs wz.36
to FR, 1938: 20 000 pcs ammo 40 mm
to NL, 1938: 48 pcs (same guns)
to NL, 1939: 40 pcs wz.36
to UK, 1939: 150 pcs wz.36 (not finish / war)

Thank you for the info, whats your source btw? Im a bit confused on the L/43 guns too as acording to the researcher Maciej Tomaszewski the polish never reived any L/43 guns.

Also could u clarify some things. What does (official Peru) mean? Where they meant for Peru or something? And (same guns) for the Netherlands?
