Help identifying new to me Singer 111W

[drc9723]

I recently purchased a Singer 111W???  (It’s missing the model number tag)
I initially thought it was a 111W101, but I’m not certain.  I do own another 111W101 machine and this new machine is very similar, but there are a few differences...

the main difference I’ve found is the lower thread guide.  My old 111W101 has a two piece guide, whereas my new 111W??? has a one piece guide (part #224040). 

After digging through lots of pics on google, I’m wondering if I may have a 111W103... 

Would anyone be able to tell me the difference between a 111W101 and 111W103. 

The new machine seems to be able to sew slightly longer stitch length (4 vs. 5 stitches per inch)

Foot lift height is about the same on both machines, approximately 3/8”

Thanks in advance
