Hi and welcome
Great looking bike, i hope you have many years enjoyment from it. Two things perhaps you ought to be aware of, one already touched on.
First, Wet sumping, you will only get an accurate level in the oil tank after you have ridden it at least 3-4 miles, make a mental note of the level at the end of your journey and when you put it away. Then when you go to start her for your next ride, check the level again before starting, if its dropped, don't be tempted to fill the tank prior to starting unless you have drained the sump. If you top up the oil tank and there's already a pint or two in the sump you will be in a right mess.
Secondly, I wouldn't want to worry you unduly but the only real area of concern I would have on using an unknown A7/A10 is any possible wear on the timing side bush. If its worn, oil pressure to the big ends is reduced which isn't good as you know. Its easy to check - remove the RH exhaust and gear lever, remove the timing side cover catching the oil in a bowl. You will see the end of the crank and if there is more than a few thou play up and down, it will need an overhaul. I know it sounds a lot of work but as they say - a stitch in time etc. If its OK you will have confidence in it. I found wear in the bush when I bought mine and overhauled the engine soon after. Now I have full confidence in it.
The main thing is enjoy it.
