Schwinn paramount ID help

[GTs58]

Or, if you rotate the photo 180, it would be 430 with an upside down 3...this would make more sense in terms of the frame details (oval lugs, flat angled seat stay caps, etc). I'd propose the 'LA' appears to be unrelated to the serial number, as the "A" stamp is smaller and serif free; I think the true early 'A' frames have the 'A' being slightly larger than the numbers, and with serifs on the bottom legs. Also, I think the earlier 'A' serials had the '3' as a fully curved number, while the later three-digit series without the 'A' had the '3' with a pointed top and curved bottom font...will have to check to verify that, however. FWIW....(addenda) I looked at all the 400 numbered Paramounts that I have serial number photos of (11 of them) and in every case the number is read as if the bike was standing upright on the rear wheel (bottom of the numbers towards the rear axle), which reinforces my assumption that this is 430 with an upside down 3.

That seems to be the case here. And if fact, the frame would have been a 1951 build according to the old Registry.
