My "new" locomotive

[SDP45]

I now have my first locomotive. Not really my first, as I have had a few hundred in the past. It is my only current locomotive. An 0-4-0T.

Non powered model by Hobbyline, manufactured by John A. English & Co., Inc.-Morrisville, PA. The instruction sheet said it cost $0.98 back in the day. I paid $1.00.

It does not need much glue, as all the parts fit without it, so I put it together to make sure all was there before washing and painting. It is missing the pilot/footbeam on the front.

Any idea when this little guy was produced?
