The relays look similar to the ones my 1301 uses to

to the front panel indicators and peripheral interlocks (so mine only
switch at human speed). Even the markings on the relays look very
familiar. I hope they are more reliable than mine though, as the machine
seems to be using them for actual computations. I suppose they would be
fine with routine maintenance, usually consisting of dragging a bit of
punched card between the closed points.
Well at a 2 sec add time, I don't expect relay problems.
Still if the photo is of the whole computer, it is a small
machine for a valve system.
