Conn 6M Ladyface (1946) info

During WW2, Conn produced only a very limited number of saxophones: the factory was almost entirely used to produce, in particular, altimeters for the US Air Force. Most of the saxophones built between late 1941 and late 1945 were intended for US military bands (these then had the US engraving on the bell) and special orders. 
From late 1945/early 1946 (after the end of WW2), production in the Conn factories was converted again for musical instrument production. The saxophones were identical to pre-WW2 instruments, i.e. with rolled tone holes. However, the VIII identification disappeared from the body and neck. No info is available as to why this VIII engraving disappeared in 1946. 

MROsaxophones overhauled a Conn 6M Ladyface with serial number 316560 in early 2023 (MRO ID : AS107). This sax was built in the first half of 1946. This was of course the perfect opportunity to compare the sax with a pre-WW2 6M Ladyface (with VIII stamp). 
I can be quite brief about this : there are no differences between the two saxes. They are completely identical. So there is no difference between a pre-WW2 6M Ladyface and a post-WW2 6M Ladyface (with rolled tone holes).
