Hi,
I have a size 54 (very rare) silver Pats authentic - Gronk, and a 2001 (the sought after El Salvador made "helmet tag" - when Reebok made their best jerseys) Broncos - I have both a Griese and a Romanowski, both the blue / orange team colors.
I have most of the others (a signed 2001 Alexander Seahawks (when they still had the old 90s style), Texans, 99 Bills and throwback Rams - but they are all size 50s, unfortunately. I'll double check, but pretty sure they are 50s.
Let me know if you are interested, or would like pictures.
You can check the feedback - I am a long-time member here with a proven track record of sales, so you have nothing to worry about!
Thanks,
Russell
