I also got myself an Invicta 1M today! It looks well used, but technically it seems to be all good. Ofcourse I'm going to give it a big checkup, plus some modern day mods, before using it. I already have a great milling machine, but every now and then I still missed a small shaper for the odd jobs (had one years ago, sold it when I moved, regretted it ever since).
It's almost the same as an Alba 1A, both are made by Elliott.
Pretty straightforward little machines, great for the home workshop.
Shapers may be totally, hopelessly, obsolete in industrial workshops but like power hacksaws can be really handy for the one man band because they can be left to get on with things whilst you do something else. It maybe slow but its all time won to do something else. I'm pretty much never waiting for either to finish.
My Elliot 10M, younger brother to yours, sees regular use cleaning up rough stock, knocking mill scale off and bringing bar or hacksawed plate down to nice true size.
The ability to effortlessly bring rough material down to a finish that polishing would spoil when fitted with a sharp tool is endearing.
One thing I do need to figure out is how to add an automatic cutting oil dispenser. I have best part of 10 ft of 10" x 1" steel bar in stock, got for various things, that most definitely wasn't the spec I ordered. Refuses to take any sort of finish dry in shaper or mill and is very hard on milling cutters. Hand squirting cutting oil lets the shaper give an OK finish but its wasteful, messy, and defeats the object of letting the shaper do its thing alone. Guess I need a little auto-squirt dooby operated at the beginning of each stroke.
I found that only the front end of the table protrudes about 1" outside of the leaking tray, so I will probably fabricate something to channel the cutting oil / emulsion back onto the tray. And then I just put a small universal pump with a reservoir underneath.
I saw an Alba on Youtube that had a spray mist setup on it.
But I'm not a big fan of those myself.
