Hello, I registered some time back when I started my project & then got sidelined by life so I guess I'm an old new member. I'm restoring a Fry 5 gal. MW I inherited from my late father. I feel fortunate that I have the original glass cyl. & what I believe is the orig. globes & the cage. I'm trying to figure out is this a model 17 or 117? What I think is the s/n on the base is Q-1603751-01. I would also like to know aprox. what yr. it was made or was in service. I tried sending some pictures way back when I registered with a dig. camera & it was a pain in the ask, but now I have a smart phone & I'm sure it's easier. Any help would be appreciated, thank you.
