I missed this Post while away guys, so here goes some info Mick asked me for in a much earlier Post. Because our earliest Ladd Model Works Guide from 1967 gave no interior color on this 38B, I can only say that my personal experience is that a possible pre-production Vauxhall Wagon with pure white seats was the first to be sent to our U.S. distributor Fred Bronner in New York. I held this original model in my hands in 1969 and had 2 different chances to own it myself. I am sure it had black plastic wheels, so it MAY have been the 'knobby' 8X18 Nick has listed as his code 1 for this model.
I regard my own 8X18 'Knobby' BPW Wagon as the earliest variation I now own, pre-dating the finer 9X20 GPW wheels. I believe Antonin's 9X20 GPW is very rare, we have never owned one of these. The pure white interior from Bronner's display had Black wheels, so I believe Nick's Guide is now accurate in my opinion.
I can also state that both color interiors were found packaged together in our later U.S. shipments, and that Nick's timeline of these coarse small knobby wheels leading to the later finer 9X24 tread tires is also correct. Why these wheels were made in both Black and in gray plastic early on, I cannot say. I can only add that I have examples of the 9X24 GPW with 'Fat' Tires, and also with 'thin' 9X24 GPW with green plastic seats. We also have two examples of 'Error Pieces' with 'thin' tires on the rear axle, and with 'fat' tires mixed on the front axle.
In it's later form the 38B came with either light or dark red interiors, and also with either thin or thick fine 9X36 BPW on them. Perhaps Antonin has those 2 very different tire widths listed on his proposed listing?
The very large 10X36 GPW are very hard to find in any condition, I suspect George's could have come out of a mutual friend's collection he is liquidating. You outbid me on that one George if it was John's....
For the first time in my life I have to say I like Nick's present listings as they are over my friend Antonin's more organized version......Is Nick's Guide Confusing?, a bit. Accurate? VERY! They agree with kwaker's memory and experience on these 38Bs as being All mixed up as found in our U.S. stores............kwakers
