Help needed identifying these shock absorbers
 

These shock absorbers are fitted to my 1930 Chrysler model 70 here in the UK. These are pictures of the front right. Number 39579 They are not original equipment however they are on the car and look of the period. If I am going to get the renovated I need to know the make and model number.Can anyone help please?

I can't help identify but I bet there reliable.
The lower picture with the part number has mark's on it like a pipe wrench was on it.

1937 Buick... ??

This is the answer to my query regarding Shock Absorbers fitted to my 1930 Chrysler Model 70. The answer provided by Apple Hydraulics.I am assuming that Chrysler might have fitted these to their export models. “Shocks like yours used for a year or two on big cars like Packard or Pierce Arrow or Chrysler (with different arms for every application). This "version 1.0" is replaced with shocks that have plugs on both ends of the body and, in late 1930s with shocks like 1941-49 Cadillac rear (for example, see pictures on https://www.applehydraulicsonline.com under Cadillac). All measurements stayed same (body dimension, spacing between mounting holes).”
