Help Identify 9u hydraulic parts

Planning to due some work on one of my 9u’s And one of the projects is fixing hydraulic leaks. Tractor used to have a blade before I got it, serial number in 25000 range. Are the parts in the pictures actually Caterpillar parts or a farmer creation? If not original parts I mar be inclined to remove them as I am using the tractor for farming only. Lever goes forward to a valve up by the pump, block on the side is a flow control valve I think. Thanks for your help, Mike[attachment=55925]2D8095DE-40CD-4C60-8928-E1F500BEEC81.jpg[/attachment][attachment=55924]158469BD-7E40-4540-9FBF-6089167529FB.jpg[/attachment][attachment=55926]82F89D35-7507-431A-8564-E10E8D9DB67B.jpg[/attachment][attachment=55927]799C366B-067F-4CD4-AD6E-4D9A9BA0A982.jpg[/attachment][attachment=55928]86E1BDD2-715E-49AF-933B-1C2D1FD340B6.jpg[/attachment][attachment=55929]39DBFA8F-B405-4243-AE41-AC2CA74BC2B4.jpg[/attachment]

Can't quite read the pump tag or valve ID. Might be Vickers stuff but definitely not original Cat.
