Use an inspection mirror and check the top of the power assembly for details.
I'd guess Danfoss due to the position of the superheat adjustment.

Looks like a Parker to me,

Have a look on google images, great for finding stuff you know what it looks like but not who makes it.

or an Alco, the phial looks more like the one in your pic.

could be an old danfoss TXV what gas type is this system? As stufus said with the position of the superheat adjustment i would sway towards it being a danfoss. The phial is different to the standard types but i think some of the older models had phials like that.
i could be wrong though check it with a mirror !!!! if it is an old danfoss you would be able to get a danfoss valve to replace it i would expect.

degas,cut it out and go shopping

do not worry about type that expansion. that is very old type because inlet is nuts and outlet welded type and is a external type, So
you can get type of gas from label units or color of top of expansion or comp. and size of that from compressor size to put new one on it

Don't think its Danfoss as the capillary would be stainless too with the stainless bellows, older ones where copper but chrome plated.

Also the hex nut shape where the equalising line goes in doesn't look Danfossy to me either.

A small mirror on a stick is handy for looking around the back of things for model numbers.

Form follows function so they do all tend to look similar!

I personally would do exactly as mbc says, confirm gas and compressor and resize it and use one off your van, the liquid inlet flare may need renewing and possibly a new piece of pipe brazing in.
