Carey,
I have a scratchbuilt model of a PRR ND cabin that has the name "J. H. Bramble" lettered on the bottom along with the date 1-31-56.
I had never heard of him before I saw your post on the "O1". I think this caboose model is also 17/64 based on the measurements I just took. It seems to be a scale foot too wide and a scale foot too long.
I didn't reaslize this was 17/64 until I got curious after your post.
