I am currently restoring a Gilbert & Barker (G&B) model 177. This pump is really tall with the visible gas cylinder and should look great when fully restored. I am struggling with the brand choice and the related colors to paint it. I think that decision will depend on which globe I buy for it. To that end, I see on various web sites globes for sale that are 15” or 16” and even smaller sizes. Can anyone advise me what is correct for my pump?? What are we measuring? The lens or the globe body size? Is there a specific size requirement for the base or all the globe bases the same size? Are There any references available on the period correct globes to use or is this just a process of looking at vintage pictures? On a separate but related subject, are there any “pump junkyards” out there where I could find a few internal parts I am missing? Sorry for all the questions but I am new to this and any help would be appreciated! Thanks - Jim
