sjgardiner@javierl7874 thats a very good question. The Porter was active for sale when I looked at the product page, but for some reason it wasn't showing as such. I've reset it and it should be available for purchase now.
sjgardiner Thanks for your kind comments on the model. I will update the listing, but the parts were mostly out of my scrap bin or from 0.020 brass rod. The best options that should be available to order either from the supplier or Walthers are below:
Globe Valves - http://www.bowserorders.com/.sc/ms/sch/ee?search=globe+valve&go.x=0&go.y=0
Bell - http://www.bowserorders.com/.sc/ms/dd/ee/12588006/Cal%20Scale%20HO%20Bell%20Ball%20Top%20Rigid
sjgardiner Thanks, and yes, i realize there is more than just re-scaling the drawings. Believe me, i've been asked that enough times with why things in my store in HO Scale aren't in N Scale as well! I look forward to seeing them when you've had the time to do so.
sjgardiner Have you given any consideration to re-scaling this and the tow bar to 1/144 scale? You offer the tugs in that scale, and i've been considering ordering them as i'm working on a diorama in that scale and looking for GSE to complete the scene.
sjgardiner Thanks thbguy, hopefully if you order it someday it will look good on your layout! I will eventually be doing Cabin D, i haven't started it beyond getting a base foundation measurement for another project. As i'm sure you can appreciate, this isn't the time of year for measuring a two storey structure outside!
