Hi, after looking on the vintage trailer gaskets website for reference, I'm not finding my window model numbers. The only numbers I see etched in the aluminum is the number 148 and the number is located on all the moving pieces that hold the window panes. Here are some photos for reference. Let me know if you can help. Otherwise I'll have to order gaskets by looks. Thanks.
Thanks for the advice. I did email some pictures to vintagetrailergaskets.com. I was emailed back right away from a very helpful individual. He said they indeed looked like series 1 and series 2 Philips windows but couldn't be exactly sure. I am mailing him samples of my gaskets and he will match them up appropriately. It is pretty cool that I am able to do such a thing.
