A couple of years ago I pulled it out and added some detail, and painted the body - still a 1P that ran on the S&D, but in LMS black with red lining.
I thought about rebuilding the original chassis (silk purse, pigs ear comes to mind) and was about to start a chassis from scratch when that nice Mr. Newitt announced he had a produced P4 sprung chassis for this kit.
Serendipity, and my order went out across the ether... A week or so later a package arrived here in Canada.
This shows the difference 40 years makes (Original Craftsman chassis side - lower), although for this photo I had only folded up the chassis to check clearances in the body. (Filing of the body will be required

My initial impressions are very good, the nickel silver etches are excellent, the instructions have a couple of minor errors, but there are photos which help clarify things. http://website.rumneymodels.co.uk/wp-content/uploads/2018/04/LMS_1P_Chassis_Instructions_-_Craftsman_Version.pdf
I would suggest that you don't start with a finished, painted body like I have, especially if you want to correct the cab interior - There will be more work involved trying not to ruin the paint.
More to come...
