I bet that rod is to hold the brake housings off the HT. A paint saver. Yes, that edge will suffer, but that is all.

And 853 was the last, best, strongest of the Reynolds alloy development before the 9-hundred SS series. Very good stuff. You can make a very light frame from it. Not easy to work with and Reynolds (at least used to) requires builders to get special training and certification to buy it.
