I can understand your intention very well. my husqvarna M 46 came d&t so it was clear for my to use the situation and mounting a scope on it. probably would not do it if the rifle was without the holes in the receiver.
a period scope is a must in my eye's and they are easy to find here on ebay or egun. something in the class of a zeiss ziel 4. the side mount is a also a good option.
ok, I had to cover something and the suhl claw mount was the only way.the scope I got was an old oigee 4x that comes with the feet's.
my gunmaker had enough old parts and so it goes very cheap.

yes, he set the front base much to high and must change it again.

EAW make such old style side mounts http://www.eaw.de/eaw/webkatalog/drZf_21_AM_seitl_M.pdf

only pic of a swede with a side mount I found just now but it was very common and looks very pc
