Regarding the period Fiamme and Mavic, as mentioned above the Mavic seem really hard to come by. I have been looking for a 32h to pair a nice 40h I have for months, possibly even a year. Hilary Stone does have some, but unless he's unearthed more since I was there, what he has would suit builds with more patina.
As far as I remember without checking, the Longhi patent expired in 1959 - so #2 would be good to around then plus a few years for stock to run off. The later versions #4-6 come up reasonably often, especially 36h, but good condition #2 and #3 are hard to come by.
Thanks for the advice, I think I will need to pick one or two different rims and then try and get a pair eventually or get lucky and find a pair of 32 & 40. The Fiamme timeline is new to me and very useful.
@SideshowBob There's a 40h Module E2 on Ebay at the moment (has been for maybe a month). IMO £80 is a lot to pay, so I have been doing my best to ignore it! https://www.ebay.co.uk/itm/1-NOS-MAVIC-MODULE-E2-700c-40-HOLE-CLINCHER-RIM/392463508327
Other 40h sprints do come up, not a lot and not often sexy ones. There are a couple of 70s/80s Monthelery Route listed at the moment https://www.ebay.co.uk/itm/NOS-Mavic-Monthelery-Route-Tubular-Road-Rim-Silver-40H-700c-622-21mm-390g/333142231526?hash=item4d90d309e6:g:BxIAAOSwOVlcAA7h and it should be relatively easy to find matching 32h fronts. Again IMO these would look good with decals removed and a bit of a polish - they are at the more robust end for sprints.

If you haven't seen this, there is good info on trying to get the 'right' Fiamme for your build https://www.bikeforums.net/classic-vintage/781480-fiamme-red-timeline-start-please-join.html

Repro decals are available from a few places, but as far as I know Cyclomondo do the best, you'd want H for #2 http://cyclomondo.net/USERIMAGES/Fiamme%20B(1).jpg
