I am interested in getting more info about the Italian "Series 5"
fighters of WW2 (Macchi MC. 205, Reggiane Re. 2005, Fiat G.55). Some
specific questions:

1. Did any Macchi 205's have 20mm cannons installed /inside/ the
wings, or did cannon-equipped 205's only have them in under-wing
gondolas? My sources are not clear on this.

2. How many rounds of ammo did the cannon-equipped MC 205 carry for
each cannon?

3. My understanding is that all Italian planes had "reversed" throttle
controls, i.e. the pilot pulled the throttle control back to get more
engine power, and pushed the control forward to cut engine power. Were
any of the Italian 5-series fighters modified to have the throttle
control operate the opposite/"standard" way when exported to other
nations (for instance, when German pilots supposedly used the Re.2005
over Berlin)?

4. I have read that the limited-production Re.2005 was considered the
best handling/most maneuverable/best performing plane of the three
Italian fighters at low-to-mid altitudes. I have heard offhand that an
Italian pilot who flew both the Spitfire VIII and the Re.2005 said
that the Re.2005 was much superior of the two in this respect. Since
there is so little information about the Re.2005 out there, can anyone
verify/add to this? Was the 2005 really that good? Did the plane have
any vices (I've heard about some sort of structural problem?)?

Thanks for any help...
